Abstract
A linearly polarized upconverting optical signal at optical frequency νand a propagating input signal at frequency νare combined by an input beam combiner to copropagate through a nonlinear optical medium and generate upconverted optical signals at one or both sum or difference frequencies ν=ν+νor ν=ν−ν. The orthogonally polarized upconverting and upconverted optical signals are separated by a polarizer, and the upconverted optical signal is preferentially transmitted to a detection system by an optical filter. The input signal is modulated to encode transmitted information, and that modulation is imparted onto the upconverted optical signal. The detection system includes one or more photodetectors, receives the upconverted optical signal, and generates therefrom electrical signals that are modulated to encode the transmitted information.
