Description
Summary:A new photomixer based on the nonlinear behavior of an electro-optic polymer material is proposed here. The microwave frequency is generated by mixing two optical signal waves propagating simultaneously inside an optical waveguide made of the crosslinked PMMA-DR1 electro-optic copolymer; the cladding layers are made of NOA material and the microwave signal is collected on a microstrip line. By matching the velocities of the microwave signal and of the optical signals it is possible to create constructive mixing in a traveling-wave configuration at more than 60 GHz. If one of the optical waves is modulated by an informative signal, the microwave signal will infer the modulation
