My device is slotted waveguide based THz modulator where I will be using GermaniumSelenide as 2D material in the slot of the signal line which has light sensitive conductivity. For light source I'm using Gassian sourcem of wavelegth 300nm to 1000nm with varying amplitude. With incidence light its conductivity changes by which modulation happens. I also need to pass a THz signal through the signal line, for that I'm using Plane wave source of Frequency  60GHz and 220GHz. I need to see change in conductivity in GeSe but it is not changing for what ever wavelength of the light.
