Jul 7, 1990 Abstract-Theoretical analysis on second-harmonic generation phase matched with gratings in channel waveguide are presented from the viewpoint of device design. The analysis includes cases where efficiency is high and residual phase mismatch is involved. Nonlinear coupled mode equations, with

Abslruct-A theory for the initial rate of second-harmonic generation (SHG) in planar optical waveguides for phase-matched and nonphase- matched cases is derived. The derivation is carried out both by a ray treat- ment and by a wave treatment and the results of the two are compared.
A theory of optical second-harmonic generation in a slab waveguide with a nonlinear dielectric core is presented; two types of second-harmonic generation, the guided-mode and the Cerenkov-radiation types, are systematically treated on an equal basis. We have obtained exact analytical solutions for the field distribution

A theory of optical second-harmonic generation (SHG) in a dissipative slab waveguide is presented, where Cerenkov-radiation-type SHG and guided-mode-type SHG are treated on an equal basis. Analytical solutions of the field distribution are obtained for TE-mode second-harmonic waves generated in a slab waveguide
