InGaAs photodetector with integrated biasing network for mm-wave applications

Abstract
Xi A waveguide integrated photodetector with an integrated biasing network is presented. The external responsivity amounts to 0.3 A/W while the bandwidth is 70 GHz. The integration of a matching resistor significantly reduces the output standing wave ratio. Application of the photodetector in a mm-wave system experiment is demonstrated. Linear operation at 64 GHz up to power levels of +10 dBm was achieved
