Generation of microwaves by mixing two optical frequencies in a nonlinear crystal: a novel approach to high-bandwidth optical mixers.
Optical mixing of waves separated in frequency by many gigahertz can be accomplished by allowing the waves to mix in a nonlinear medium to generate microwave difference frequencies. This basis for high-bandwidth optical mixers is demonstrated by mixing optical frequencies approximately 4 GHz apart of a pulsed dye-laser beam at approximately 660 nm in a LiTaO(3) crystal to produce readily detectable microwave power at approximately 4 GHz.
