摘要: We demonstrate broadband wavelength conversion of a 40 Gb/s return-to-zero signal using four-wave-mixing (FWM) in dispersion engineered chalcogenide glass waveguide. The 6 cm long planar rib waveguide 2 μm wide was fabricated 0.87 thick film etched 350nm deep to correspond design where offsets the material leading near-zero C-band and phase matched FWM. reduced dimensions also enhance nonlinear coefficient 9800 W-1km-1 at 1550 nm enabling shorter device. In this work, we 80 conversions with 1.65 dB power penalty bit-error rate 10-9. Spectral measurements simulations indicate extended operation is possible.
