Time-domain analysis of wavelength shift in a ZnTe slab due to electro-optic effect in THz
In this research, propagation of an optical signal through a ZnTe slab which shows electro-optic (EO) effect for terahertz frequencies is analyzed. We assume that the optical signal and the terahertz modulating signal are simultaneously present in the ZnTe slab. The slab is modeled by its nonlinear susceptibility in a one-dimensional Finite Difference Time Domain (FDTD) formulation. Using the FDTD analysis, we demonstrate that the optical signal will experience a frequency shift in the presence of the terahertz signal. The frequency shift predicted by this method of analysis is in agreement with a recently reported experiment.
