Abstract
In waveguide photodetectors the bandwidth and the quantum efficiency may be specified almost independently because the absorption of light is in the longitudinal direction whereas the current flows in the transversal direction. Then, these devices may combine high bandwidth with high quantum efficiency. In this paper a detailed numerical analysis of the frequency response of waveguide photodetectors is presented. The calculations show that the capacitive effects limit the bandwidth but that by an appropriate choice of a series inductance the maximum bandwidth almost doubles.
