Abstract

We have successfully demonstrated all-optical wavelength conversion of a 640-Gbit/s line-rate return-to-zero differential phase-shift keying (RZ-DPSK) signal based on low-power four wave mixing (FWM) in a silicon photonic chip with a switching energy of only ~110 fJ/bit. The waveguide dispersion of the silicon nanowire is nano-engineered to optimize phase matching for FWM and the switching power used for the signal processing is low enough to reduce nonlinear absorption from two-photon-absorption (TPA). These results demonstrate that high-speed wavelength conversion is achievable in silicon chips with high data integrity and indicate that high-speed operation can be obtained at moderate power levels where nonlinear absorption due to TPA and free-carrier absorption (FCA) is not detrimental. This demonstration can potentially enable high-speed optical networks on a silicon photonic chip.

Four-wave mixing in a silicon nanowire. A pump wave interacts with a signal wave and generates an idler wave at a new frequency of 2ωp – ωs. The silicon nanowire is fabricated on a SiO2/Si substrate, inversely tapered at each end and embedded into a larger polymer waveguide for low loss interfacing with optical fibers.

(a) Simulated GVD and (b) FWM conversion efficiency of the silicon waveguide with 450-nm width and different heights (200 nm, 240 nm, 300 nm). Inset. Measured conversion efficiency at the pump wavelength of 1550 nm for the waveguide with cross section 450 × 240 nm2.

(a) Free-carrier induced nonlinear absorption for the 3.6-mm long silicon waveguide with cross section 450 × 240 nm2. The insertion loss is measured for different coupled peak powers. It is clearly shown that when the peak power is below the TPA threshold (~39 dBm) the nonlinear absorption is almost negligible (<1 dB nonlinear loss) and when the peak power is above the threshold the nonlinear absorption increases significantly. (b) Optical spectra at the output of the silicon waveguide for different input powers. For a power above the threshold, the free-carrier induced spectral blue-shift and a broadening of the spectrum is observed.

Experimental setup for all-optical wavelength conversion on a silicon photonic chip. A 640-Gbit/s transmitter consists of a short pulse source (600 fs of FWHM), a Mach Zehnder data modulator (MZM) and an optical time-division multiplexer (MUX). The wavelength converter consists of a silicon chip, a CW laser, an erbium-doped fiber amplifier, an optical bandpass filter (OBF), a polarization controller (PC) and a filtering subsystem. (a) Spectrum at the input of the silicon chip. (b) Spectrum at the output of the silicon chip. (c) Spectrum of the converted signal after filtering and amplification. (e) Autocorrelation trace of the input signal. (f) Photograph of the silicon photonic chip. (g) Autocorrelation trace of the converted signal.
