Abstract:
A coating (10) between a nonlinear crystal (5) and a silicon prism coupler (9), prevents transmission of radiation scattered within the crystal (5) by filtering out frequencies outside the silicon bandgap to avoid free carrier absorption, but transmits THz frequencies that correspond to the bandgap.
