Abstract
An InGaAs PIN photodiode was vertically integrated with an inverted optical rib waveguide in InGaAsP. Guided light was transferred to and absorbed by the photodiode at a rate of 0.07dB/μm. For detectors with sufficient length (>300μm) a responsivity of 0.81 A/W was achieved at 1.3 μm wave-length.Keywords
