We experimentally demonstrate wavelength multicasting based on free carrier dispersion effect in a silicon mode-split microring resonator with a radius of ~10 ??m. The mode-split of the resonator is caused by mutual coupling between the co-propagating and counter-propagating modes inside the microring resonator, which is induced by the periodic grating-like roughness of the sidewalls. The free carriers...
We propose a prototype of a silicon-chip-based frequency quadrupling system integrating a single-drive silicon Mach-Zehnder modulator and a microring resonator. A proof-of-concept demonstration of 40-GHz millimeter-wave signal generation using 10-GHz driving signal is experimentally provided.
We experimentally demonstrate optical signal processing in silicon ring resonators, including slow and fast in silicon rings, optical delay of digital and microwave photonic signals, dense wavelength conversions/multicasting, optical up-conversion, format conversions, temporal differentiation, and bio-sensing.
