Analysis of Tunable Terahertz Generation in Gallium Phosphide Using Difference Frequency Mixing
Keywords:
Difference Frequency Generation, Terahertz Frequency and Gallium Phosphide.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.
