23 September 1994 Artful waveguides for frequency doubling
Author Affiliations +
Two kinds of poled polymer systems, DR1/PMMA and p-NA/PVA were set in artfully designed frequency doubling multi-layered waveguides. (Ti2O5)x/(SiO2)y glass which was adjustable on refractive index by varying the ratio, x/y was inserted between poled polymer nonlinear optical layer and glass substrate to optimize conversion efficiency of frequency doubling. Also a face-to-face structure of poled polymer film was applied to frequency doubling waveguide in Cerenkov-type phase matching. In this structure d33:-d33 counter-parallel distribution was effective for overlapping of both fields. Finally ridge-type channel waveguide was prepared for high efficiency SHG waveguide.
