A mode-engineered hybrid III-V-on-silicon photodetector

View publication


We report on a novel III-V-on-silicon-photonics device architecture with an excellent modal overlap with the III-V material. Using this concept, we demonstrate hybrid photo-detectors with very low dark currents, a responsivity of up to 0.8 A/W and a low capacitance of 0.2 pF.
