The authors present an InP based pin-photodetector with an integrated passive optical waveguide using evanescent field coupling for operation in the wavelength around 1.55 {micro}m. The passivated devices are fabricated employing a single MOVPE run and a self-aligned metallization process in order to achieve reduced series resistances. They are monolithically integrable in photonic integrated circuits with optical functionality as well as with high-speed electronic amplifier circuits. The detector exhibits a polarization insensitive internal quantum efficiency of about 90% and a transit time limited high-speed behavior. The electrical cut-off frequency amounts to 45 GHz and is maintained up to high input power levels.
