Future high-bit rate optical communication networks operating at bit rates above 40 Gbit/s and, in particular, wireless cellular mobile communication systems based on an optical distribution network necessitate the availability of accordingly fast, but also highly efficient photodetectors especially for the 1.55 /spl mu/m wavelength region. We present an InP based pin-photodetector with an integrated passive optical waveguide using evanescent field coupling for operation in the wavelength around of 1.55 /spl mu/m.
