Abstract :
40 Gbit/s photodetectors require high bandwidth at high power levels, as supplied by waveguide-integrated p-i-n diodes on InP. By monolithic integration of a spot size transformer a responsivity of 0.5 A/W is achieved and fiber alignment tolerances are increased by one order of magnitude.
