Fabrication and characterization of corona-poled NPP polymer waveguides for second harmonic generation

A polymethyl methacrylate (PMMA) and N-(4-nitrophenyl)-(s)- prolinol (NPP) side-chain polymer waveguide was developed and corona poled for second-harmonic generation (SHG) devices. The nonlinearity decreases with time in the corona poled NPP polymer waveguide were characterized by the variation of the extraordinary and the ordinary refractive indices with time. The Cerenkov-type green second-harmonic (SH) radiation at 532 nm was observed successfully.© (1998) COPYRIGHT SPIE--The International Society for Optical Engineering.
