Polarization manipulated all-optical cross-wavelength data inversion in C-rich SiCx micro-ring

Abstract

With the use of a two-photon-absorption-free C-rich SiCx ring waveguide, the polarization manipulated all-optical format inversion of 12.5 Gbit/s pulsed return-to-zero on-off-keying (PRZ-OOK) data stream is demonstrated through the nonlinear Kerr switching induced wavelength conversion process. The nonlinear refractive index of the low-temperature PECVD synthesized C-rich SiCx is up to 1.37×10-12. The TE- and TM-mode polarization dependent transmission spectrum of the C-rich SiCx ring waveguide with wavelength separated spectral notches at extinction ratio of 7dB can be manipulated via detuning the orthogonal polarization of the incident pump pulse. Moreover, the modulation depth can be enlarged by more than 3dB. The all-optical wavelength converted and inverted PRZ-OOK data stream at 12.5 Gbit/s with corresponding ER of 7.8 dB, SNR of 8 dB and BER of 2.85×10-10 is obtained, which confirms the functionality of such C-rich SiCx ring waveguide based pure Kerr switch for implementing ultrafast data processing in all-optical integrated circuits.
