Optics Express | 2018

Segmented waveguide photodetector with 90% quantum efficiency

Qianhuan Yu; Keye Sun; Qinglong Li; Andreas Beling

We demonstrate a novel InGaAsP/InP segmented waveguide photodetector based on directional couplers. By matching the imaginary parts of the propagation constants of the even and odd modes, we designed a photodetector with 6 elements, each with an absorber volume of only 19 μm3 and a bandwidth of 15 GHz, that has an internal quantum efficiency (QE) of 90% at 1550 nm wavelength corresponding to 1.13 A/W.
