Abstract

Abstract : Polarization-manipulated all-optical format inversion of a 12.5 Gbit s −1 pulsed return-to-zero on-off-keying (PRZ-OOK) data stream is demonstrated through the nonlinear Kerr switching-induced wavelength conversion process. Abstract : With the use of a two-photon-absorption-free C-rich SiC x ring waveguide, the polarization-manipulated all-optical format inversion of a 12.5 Gbit s −1 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 low-temperature plasma-enhanced chemical vapor deposition (PECVD)-synthesized C-rich SiC x is 1.37 × 10 −12 cm 2 W −1 . The TE- and TM-mode polarization-dependent transmission spectrum of a C-rich SiC x ring waveguide with wavelength-separated spectral notches at an extinction ratio of 7 dB can be manipulated via detuning the orthogonal polarization of the incident pump pulse. Moreover, the modulation depth can be enlarged by more than 3 dB. An all-optical wavelength-converted and inverted PRZ-OOK data stream at 12.5 Gbit s −1 with a corresponding extinction rate (ER) of 7.8 dB, signal-to-noise ratio (SNR) of 8 dB and (bit error rate) BER of 2.85 × 10 −10 is obtained, which confirms the functionality of such a C-rich SiC x ring waveguide based on pure Kerr switching for implementing ultrafast data processing in all-optical integrated circuits.
