Abstract

In this paper numerical analysis has been carried out to study the tunable terahertz (THz) generation in gallium phosphide using difference frequency generation. By varying the input wavelengths in the range 930-1030 nm we obtained 0.1-3 THz tunable THz frequency. Theoretical dependence of THz wave power on GaP crystal length and effect of simultaneous tuning of both the input wavelengths has been studied. The simulated values of THz peak power were 0.6 W, 0.7 W and 0.48 W which were obtained at 1.3, 2 and 2.7THz respectively
