Abstract

We perform time-domain measurements of optical transport dynamics in silicon nano-photonic devices. Using pulsed optical excitation the thermal and carrier induced optical nonlinearities of micro-ring resonators are investigated, allowing for identification of their individual contributions. Under pulsed excitation build-up of free carriers and heat in the waveguides leads to a beating oscillation of the cavity resonance frequency. When employing a burst of pulse trains shorter than the carrier life-time, the slower heating effect can be separated from the faster carrier effect. Our scheme provides a convenient way to thermally stabilize optical resonators for high-power time-domain applications and nonlinear optical conversion.

The measurement setup used for the time-domain analysis. Wavelength tunable optical pulse of variable width and repetition rate are generated using a tunable laser source combined with an electro-optical modulator and an electrical pulse generator. The sample under test is mounted in a vacuum chamber on a temperature stabilized stage. The optical signal is readout using an optical oscilloscope.

(a) The time-domain response of the spiral waveguide shown in Fig. 1(a). The total length of the waveguide is 1cm in order to allow optical nonlinear effects to manifest. The waveguide is excited with pulses of 10ns length with a pulse power of up to 650μW. The repetition rate is set to 100kHz. For high pulse powers free-carrier absorption during the initial period of the pulse limits the peak pulse power in the stabilized regime. (b) Zoom-in from (a) in the high-power regime. From the fit the free-carrier life-time in the waveguide is estimated to be ~1.9ns.

(a) The spectral response of the ring resonator from Fig. 1(b) in the DWDM regime. The radius of the resonator is chosen such that the free-spectral range coincides with the DWDM channels. The sample is heated to 304K in order to position the resonator in close vicinity of the filter channels. Shown are the measured transmission spectra in the through port (red) and the drop port (black). The ring resonator is close to critically coupled with an extinction ratio of almost 20dB. (b) Zoom into one resonance close to DWDM channel 30 at 1553.329nm (linear scale). The fitted optical Q is 26,500. Low insertion loss into the drop port is achieved, illustrating that the ring is almost critically coupled to the bus waveguide.

(a) The time-domain response of the ring resonator shown in Fig. 1(b). The waveguide is excited with pulses of 40ns length with a pulse power of 300μW. Shown is the response in dependence of wavelength and time. The blue regions correspond to low optical transmission when the pulse wavelength overlaps with the ring resonance. (b) A cut through the measured profile of for a time delay of 27ns showing the optical resonance dip of the ring resonator. (c) The time-wavelength response of the ring resonator at an optical input power of 650μW, close to the ring resonance. The measured response is shown in dependence of wavelength, showing the thermal resonance tuning of the ring resonator. The generation of free-carriers leads to a rapid change of the resonance frequency which is then compensated by thermal heating.

Shown is the time-domain response of the ring resonator under excitation with long single pulses. The repetition period is kept at 10μs while the amplifier current is varied from 900mA to 1400mA. At lowest pulse power the thermal shift of the resonance during the pulse is apparent. When the pulse power is increased, competition between free-carrier absorption and thermal heating leads to oscillations during the pulse train. The oscillation amplitude increases with increasing pulse power. Simultaneously the onset of the oscillations shifts towards the beginning of the pulse, which is a signature of increased free-carrier effects. Inset: The origin of the oscillations is shown schematically. Thermal drift shifts the resonance wavelength to the right to a blue detuned wavelength. FCD leads to a backward shift and resulting oscillating thermal drift due to power modulation when the resonance passes through the pulse wavelength.

(a) Shown is the ring resonator response under burst excitation in the through port. The pulse wavelength is tuned to the optical resonance, therefore the pulse amplitude increases as the resonator heats up during the pulse train and the resonance wavelength is shifted. (b) The complementary response of the ring in the drop port. Here the amplitude decreases as the resonance wavelength is shifted away from the pulse wavelength. (c) A zoom into the pulse train showing the pulse profile of the individual pulses in the through port. (d) The equivalent measurement of the pulse profile in the drop port.

The response of the drop port of the ring resonator under burst excitation with trains of 40μs length. The width of the individual pulses is set to 1ns. The wavelength of the pulse is tuned into the resonance. The pulse period is tuned from 5ns to 200ns from top to bottom. When the duty cycle is high, thermal drift of the resonance leads to reduced pulse amplitudes towards the end of the pulse train. When the duty cycle is reduced, the temperature of the ring resonator is stabilized and the pulse amplitude remains constant.

(a) The simulated amplitude response of a ring resonator over 350ns in the through port. The pulsed driving input field is shown by the light blue profile. The input wavelength is tuned into the cavity resonance. Due to thermal heating the resonance shifts away from the pulse wavelength and thus the pulse amplitude increases. (b) The simulated temperature response of the device. The overall temperature increases during the pulse duration and drops only slightly during the dead time. (c) The simulated free-carrier density inside the ring resonator, showing free-carrier stabilization after 3 cycles. Inset: the first through cycles of the burst showing the free-carriers settling into steady-state amplitude. After three cycles the carriers have achieved equilibrium dynamics.
