Abstract

Terahertz characteristics of opto-sensitive InP based double drift IMPATT diode with and without optical radiation are studied and the results are compared with another opto sensitive semiconductor 4H-SiC based IMPATT at same operating frequency (0.5 THz) . The effects of parasitic series resistance on the THz frequency performance of the simulated InP based diode is also analysed. Unilluminated IMPATT diode based on 4H-SiC are found to perform better than unilluminated InP based IMPATT in terms of power output and efficiency. But, under optical illumination, the modulation of dynamic properties of double drift InP diode is found to be more prominent than that of SiC based IMPATT operating under similar condition. These studies reveal the potential of InP IMPATT as optically controlled high speed THz switch.
