Abstract

We demonstrate a very efficient high speed silicon modulator with an ultralow π-phase-shift voltage-length product VπL = 1.4V-cm. The device is based on a Mach-Zehnder interferometer (MZI) fabricated using 0.25μm thick silicon-on-insulator (SOI) waveguide with offset lateral PN junctions. Optimal carrier-depletion induced index change has been achieved through the optimization of the overlap region of carriers and photons. The 3dB bandwidth of a typical 1mm long device was measured to be more than 12GHz. An eye-diagram taken at a transmission rate of 12.5Gb/s confirms the high speed capability of the device.

1. Introduction

The potential for monolithically integrating photonic components with complementary-metal-oxide-semiconductor (CMOS) microelectronic circuits on one platform has created significant interest in silicon photonics [13]. This field is seen to be particularly important for the realization of next generation inter-chip data communication through optical interconnects [4]. Many silicon based photonic components have been investigated and demonstrated, including lasers [57], photodetectors on small [811] and large core waveguides [12,13], and modulators [1425]. Owing to weak electro-optical effects in silicon [26], optical signal modulation remains a very challenging task. So far, modulator devices have been fabricated using a MOS-capacitor [14,15], carrier injection [1618], carrier depletion [1923], and the electro-absorption (EA) effect [24,25]. Carrier injection in a silicon PIN diode can induce a larger index change and is known to be more efficient than carrier depletion in a silicon PN diode. However, the speed of a carrier injection device is limited by the carrier lifetime in the junction and the speed reported so far is limited to a few gigahertz unless complicated driving circuits are employed [1618].

Exploitation of carrier depletion, on the other hand, can lead to much faster devices. Early work on high speed depletion modulators is reported in references [19] and [27,28]. Since then, multiple groups have attempted to demonstrate high speed operation. Recently, a compact microring based depletion modulator that can operate at 11GHz with ultralow power consumption was demonstrated [23]. Ring-based devices, however, have to operate over a very narrow bandwidth (typically ~0.1nm), or be precisely temperature tuned. In addition to being restricted to a narrow wavelength range, ring-based devices operate over a restricted electronic bandwidth [29]. Mach-Zehnder devices, on the other hand, offer broader-band operation. Using vertical [19] and lateral [21] PN junctions, around 20GHz modulation speed has been reported. However, these demonstrations were carried out on rather short devices (~1mm length or shorter), leading to low modulation depth..To overcome these issues, the modulation efficiency, which is usually quantified by the π-phase-shift voltage-length product VπL value, needs to be improved. Previously reported VπL values of Mach-Zehnder devices are 4V-cm [19,21] or higher [20]. With high-doped PN junctions, the VπL value can be lowered down. For example, a recent demonstration of VπL value around 2V-cm has been reported using a ring-assisted MZI device [22]. However, due to the high doping level of the PN junction, the device suffers from high free-carrier loss. In this paper, we demonstrate a very efficient MZI based high speed silicon carrier-depletion modulator integrated on a 0.25μm thick SOI waveguide with a very low VπL value of 1.4V-cm. The device utilizes middle-level of doping concentration (5x1017 - 1x1018 cm−3) yet achieved very high efficiency. A typical 1mm long device can operate at 12GHz modulation speed with an extinction ratio 6dB under −8V bias and an insertion loss of only 2.5dB.

2. Device structure and fabrication

The modulator device is based on lateral PN junctions fabricated in a MZI structure. A 1x2 multi-mode interference (MMI) splitter and 2x2 MMI combiner were used to realize the MZI structure. A schematic view of the phase shifter section of the presented device is shown in Fig. 1(a) . The modulation efficiency of a MZI modulator is directly related to the phase modulation efficiency of the phase shifter. The phase change Δφ of the phase shifter can be estimated as Δφ = 2πΔΓΔnL/λ, where ΔΓ and Δn are the optical confinement change and silicon index change induced by the carrier depletion, L is the length of the phase shifter and λ is the operating wavelength. ΔΓ is proportional to the depletion width change Δx and inversely proportional to the optical mode size. From the semiconductor physics models, we know that the Δx is roughly proportional to 1/Nd, where Nd is the doping concentration in the depletion region. Further, the index change Δn is related to the doping concentrationNd [26]. Using these relations, it is straightforward to show that the modulation efficiency of the MZI modulator can be improved by: 1) using a small waveguide (larger ΔΓ), 2) applying high doping concentration (larger Δn), and 3) optimizing the PN junction position (larger ΔΓ). The device reported here has utilized all three techniques to make highly efficient modulation possible.

First of all, we choose to use a small waveguide to achieve large ΔΓ. The device reported here is fabricated on a 0.25μm thick SOI waveguide with a width of 0.5μm. The substrate was an SOI wafer with a 3μm thick buried oxide layer. The waveguide was formed by etching 0.2μm of silicon. An approximately 50nm thick silicon slab was left intentionally to create an electrical path for contact purposes. Figure 1(b) shows a scanning electron microscope (SEM) cross-sectional view of the fabricated phase shifter. It illustrates how compact the waveguide is compared to the other feature sizes of the device.

Further improvements were carried out by optimizing the PN junction. From the free-carrier plasma effect relation given in [26], it is known that the silicon refractive index change is proportional to the carrier concentrations, i.e., Δn = −8.8x10−22xΔNe-8.5x10−18x(ΔNh)0.8, where ΔNe and ΔNh are the electron and hole concentration changes inside the depletion region. Obviously, higher doping concentration can lead to higher index change, but with higher loss due to the free carrier absorption. To maximize the modulation efficiency without significantly compromising waveguide loss, we choose a middle-level p-doping concentration of 5x1017 cm−3 and n-doping concentration of 1x1018 cm−3 in our device design. We used the smaller p-type doping because holes (p-type carriers) contribute more to index change than electrons (n-type carriers). With the carefully designed doping profile depicted in Fig. 1(a), under reverse bias condition the depletion region extends mainly into the p-doped region, maximizing the index change during the operation. Further enhancement was achieved by optimizing the PN junction positional offset with respect to the waveguide center to improve the overlap between carriers and photons so that a larger ΔΓΔn product can be obtained when a bias voltage is applied to the PN junction. Simulations show that approximately 100nm offset from the waveguide center maximize the carrier-photon overlap and leads to high modulation efficiency.

Finally, to ensure good ohmic contacts, the slab regions on both sides of the junction were doped to the same concentration level as the junction area up to 0.5μm away from the waveguide. The contact areas were heavily doped to a level of 1x1020 cm−3. The metal contacts for both p and n sides were formed by depositing and patterning Ti/Al metal stacks on top of the doped areas.

3. Device performance

The modulation efficiency of the MZI-based modulator is determined by the efficiency of the PN junction phase shifter. The phase shifter efficiency was measured for a set of devices with various phase shifter lengths. The results are shown in Fig. 2 . In Fig. 2(a), the normalized response of a MZI modulator with 1mm long phase shifter for various bias voltages is illustrated. The device response is normalized to the response of a reference passive waveguide with the same length but without phase shifter. As shown in the figure, the device exhibits ~2.5dB excess loss relative to the reference passive waveguide. This includes ~1.9dB excess loss due to the doping (1mm long phase shifter at about 19dB/cm absorption loss), and ~0.6dB loss from the splitter and combiner.

The output response is then fitted using the MZI response function and the curves are shown in the figure (blue lines). The relative phase shift induced by the applied bias voltage is estimated from the fitting data using the equation Δφ = 2πΔλ/FSR, where Δλ is the wavelength shift due to the applied voltage and FSR is the free spectrum range which is mainly determined by the MZI path length difference between two arms. We also measured devices fabricated at the same time with different phase shifter lengths. The phase shift versus the bias voltage for various device lengths is illustrated in Fig. 2(b). As shown in this figure, a π phase shift can be achieved with merely 2.6V reverse bias for a 5mm long device (VπL = 1.3V-cm). On the other hand, shorter devices require higher bias voltages. For a 1mm long device, with 6V reverse bias, the achievable phase shift was measured to be 0.42π (VπL = 1.4V-cm), which is able to provide more than 4dB ER. As a comparison, with the same bias voltage the device with the same phase shifter length presented in [19] has obtained 0.1π phase shift, which is almost 4 times smaller. Significantly, the voltage-length product VπL of these devices has reached the 1.3-1.4V-cm level, which is so far the lowest value reported for a silicon lateral PN depletion modulator. Further increasing the bias voltage can realize bigger phase shift, with smaller phase shift per voltage change. For instance, the device can realize 0.5π phase shift with 8V bias voltage as shown in Fig. 2 (b), which can provide 6dB ER.

It is worth mentioning that the VπL value is not the only figure-of-merit. Device performance is also related to the loss per unit length of the phase shifter. With higher-doping concentration, it is easy to achieve a relatively low VπL value. For example, a 2V-cm VπL value has been reported in [22] with much higher doping concentrations (1x1018 cm−3 p-doping and 5x1018 cm−3 n-doping). The estimated phase shifter loss of that device can be >60dB/cm. In our case, the device we reported here is much more efficient. We achieved 1.4V-cm VπL value with 19dB/cm phase shifter loss. Nevertheless, 1.4V-cm VπL value is certainly not the limit of the PN depletion based modulators. By optimizing the overlapping of the depletion region and the optical mode, 0.5V-cm VπL value may be achieved according to our simulation. With the improved VπL value, it is possible to reduce the total driving voltage of the device to be compatible to high-speed CMOS electronic devices (1-2V). Increasing the phase shifter length can also lead to the reduction of the driving voltage. However, a careful design of travelling-wave transmission line is necessary to achieve high-speed operation [28].

The high speed performance of the reported lateral PN depletion modulator was demonstrated by measuring the 3dB bandwidth and eye-diagrams at high transmission rate. The 3dB bandwidth measurements were carried out by using an Agilent vector network analyzer. The high-speed signal and DC bias voltage were applied to the modulator device through a bias-tee and a high-speed probe. The output modulated light signal was first amplified using an erbium doped fiber amplifier (EDFA) then directly fed into the network analyzer. The system was calibrated in advance to factor out the effect of the RF system, including the cable, modulator driver, and the bias-tee. The frequency responses of the modulator devices with 0.25mm and 1mm long phase shifter lengths are shown in Fig. 3(a) . The results reveal the devices are capable of achieving 3dB optical bandwidth of 12GHz and 30GHz for 1mm and 0.25mm long devices, respectively.

The eye-diagram measurement used a similar experimental set up. A pseudorandom binary sequence (PRBS) signal with (223-1) pattern length at a 12.5Gb/s transmission rate was used. The PRBS signal was amplified by a commercial modulator driver with ~6Vpp. The signal was combined with 3V DC bias using the bias Tee and applied to the modulator. The modulated light signal was amplified by an EDFA and fed into a digital communication analyzer with an optical module. A typical optical eye-diagram for a 1mm long device at 12.5Gb/s transmission rate is shown in Fig. 3 (b) for 1550nm wavelength. A clear eye opening with >7dB ER is observed. Higher transmission rates are possible given the device 3dB bandwidth of 12GHz, which suggests that it can be operated at > 15Gb/s. However, 12.5Gb/s is the maximum capability of the pattern generator available to us. Nevertheless, the 3dB roll-off and eye-diagram measurements at various wavelengths confirm that the reported 1mm long device is capable of operating at 12GHz over a wide wavelength range.

4. Conclusions

We have demonstrated a very efficient high speed silicon carrier-depletion-based MZI modulator integrated using 0.25μm thick SOI waveguides. The VπL value was 1.4V-cm for a 1mm long device at 6V bias. With a 1mm long phase shifter, the device operates at 12GHz modulation speed with an ER greater than 6dB with reverse bias of 8Vpp. A total insertion loss of 2.5dB has been achieved, including a 1.9dB access loss due to doping and a 0.6dB loss from splitter and combiner. For a device with 0.25mm long phase shifter, we have demonstrated 30GHz optical modulation speed. Further improvement of the device performance can be carried out through fabrication process optimization and transmission line electrode design.
