In this paper, we review recent results on hybrid silicon mode-locked lasers with a focus on low phase noise optical pulse generation. Taking a high level design approach to lowering phase noise, we show the need for long on-chip optical delay lines for mode-locked lasers to reach and overcome material limits. Key results include demonstration of the longest (cavity length 9 cm) integrated on-chip...
In this paper, we demonstrate silicon evanescent lasers using a new architecture as one way to build photonic active devices on a silicon-on-insulator (SOI) wafer via low temperature wafer bonding. This approach adopts a wafer bonded structure between a silicon passive waveguide and III-V offset quantum wells. The optical mode is predominantly confined in the silicon waveguide and a small percentage...
