The performance from a high-energy Br+-irradiated InP photoconductive antenna excited at 800 nm has been investigated. The ionic irradiation into InP reduces significantly the lifetime of photo-carriers in the substrate material down to 1.4 ps without the requirement of an epitaxial layer growth. THz emitter and detector efficiency are strongly dependent on irradiation doses. It was found that equivalent bandwidth and amplitude compared with LTG-GaAs switches excited at 800 nm under the same experimental conditions.Read less <
