Silicon Waveguides for High-Speed Optical Transmissions and Parametric Conversion around 2 $μ$m

Abstract

We show that single mode Si waveguides efficiently sustain high-speed transmissions at 2 $μ$m. We report the transmission of a 10 Gbit/s signal over 7 cm with a power penalty below 1 dB. Parametric conversion in the continuous wave regime is also demonstrated using the same waveguide structure with a conversion window over 70 nm and an efficiency as high as-25 dB that can be further increased in the pulsed pump regime.
