Low polarisation dependence, 60 GHz and 100 GHz AlGaInAs waveguide fed photodiodes have been simulated at 1.55 /spl mu/m wavelength. They exhibit internal quantum efficiencies as high as 94% and 75% for 60 GHz and 100 GHz bandwidths respectively. Electrical analysis predicts better performances for AlGaInAs based photodiodes. Waveguide-fed photodiodes are shown to be very good candidates for high bandwidth applications.
