Ultrahigh speed photodiodes with -3dB frequency roll-off in excess of 100 GHz or equivalently in the time domain an impulse response with a full width half maximum (FWHM) of 5.4 psec have been developed and characterzed. These 100 GHz photodiodes have a planar configuration fabricated on n on n+ GaAs expitaxial layers on semi-insulating GaAs substrates which together with proton bombardment, have kept parasitic capacitances to ≤15 femto farads. The planar structure photodiode also lends itself easily to monolighic integration with a MESFET. The device operates at a reverse bias of -4 volts.
