摘要: Cerenkov-radiation-type optical second-harmonic generation is analyzed by using the Green function of Helmholtz equation, including nonlinear-polarization term. The numerical results agree well with those previously reported experiments. A formulation given that provides a means designing frequency doublers, which make use channel waveguides and fibers.
