We experimentally demonstrate on-chip dual-channel all-optical AND logic operations based on four-wave mixing (FWM) for on-off keying (OOK) signals in a multimode silicon waveguide. A two-mode (de)multiplexing circuit consisting of tapered directional coupler-based (de)multiplexers and a multimode waveguide is designed and fabricated for this application. Experimental results show open eye-diagrams...
We report a tunable silicon microring laser with 150 kHz line-width, above 29 mW output power and 60dB SMSR. Coherent optical OFDM 4-QAM and 16-QAM transmissions using this laser are also demonstrated.
Silicon optical modulators, one of the essential building blocks of silicon photonics technology, have made rapid progress in the last decade and start to show the competitive performances when comparing to traditional LiNbO3 and III–V optical modulators.
We demonstrate a tunable laser source based on a silicon microring. 1.1 kHz linc-width, >8 mW output power and wide tuning range are achieved. 4-QAM and 16-QAM coherent transmissions using this laser are also demonstrated.
