Abstract
A new millimeter-wave (MMW) signal generation device using a rectangular waveguide and second order nonlinear optical effect is proposed. Using a T-shaped rectangular waveguide with a suspended LiTaO3 crystal, adiabatic MMW signal injection into the waveguide is obtainable through optical difference frequency generation in the crystal. This device is easy for coupling to standard rectangular waveguide circuits compared with the proto-type devices where a nonlinear crystal is completely embedded into a rectangular waveguide. Analysis, design and preliminary experimental results are reported.
