Continuous-wave millimeter wave signals are generated at 94 GHz in a LiNbO[sub 3] nonlinear optical waveguide. Optical light with two frequency components is introduced into an optical waveguide, and the generated millimeter waves are obtained from a terminal connected to the metallic traveling waveguide. The configuration is made with a LiNbO[sub 3] commercial phase modulator. The generated signals have square-law characteristics between the output and the input power. Experimentally obtained results show that the probable candidate of this physical mechanism is difference frequency generation in nonlinear optical materials. © 2003 American Institute of Physics.
