We demonstrate concurrent multi-channel transmission at 10 Gbps per channel of a DWDM silicon photonic transmitter. The DWDM transmitter is based on a single quantum dot comb laser and an array of microring resonator-based modulators.
We report a systematic study of monolithic microring-resonator cross-connect filters with various waveguide widths and heights in silicon-nitride-on-silica substrates. Our experiments reveal that for particular deeply etched rib heights and slab heights, the microring-resonance Q factors rise nearly linearly as a function of the submicrometer waveguide width, while the extinction ratios generally...
