Abstract :
In this paper we have investigated that the ionic irradiation of InGaAs layers provide sub-picosecond carrier lifetime while preserving good electrical properties of the material. Photoconductor based on ion-irradiated InGaAs exhibits a 2.2ps electrical pulse with an amplitude of 0.65 Volts for 3 Volts polarization. So such photoconductive switches are good candidates to test high bandwidth telecom devices.
