Abstract

A copolymer of methyl methacrylate and azo-dye-substituted methacrylate is corona-poled. Cerenkov-type second-harmonic generation (SHG) of Nd:YAG laser is observed in the poled polymer waveguide even though there is strong absorption of the SHG wavelength. The total SHG conversion efficiency is 1.72 × 10-3%, and the net SHG conversion efficiency in the waveguide is 0.21%.
