We demonstrate a five-port optical router composed of eight silicon microring optical switches tuned by thermo-optic effect. The optical signal-to-noise ratio of the device on the tested routing states is over 11 dB at the working wavelength. 32-Gb/s data transmission has been performed on its 20 optical links, and eight-channel wavelength division multiplexing data transmission in the wavelength...
We implement decoding function based on two cascaded microring resonators, which are both modulated through the carrier-injection modulation in forward biased PN junctions embedded around the MRRs. Bitwise operations at 1Gbps are demonstrated successfully.
We propose an N-bit optical digital-to-analog convertor based on silicon microring resonators. As a proof of concept, a 3-bit optical digital-to-analog convertor is demonstrated at a speed of 500 MSample/s
