Abstract
Channel waveguides of a polymer with nonlinear optical properties and transparency down to 400 nm were fabricated to be used for laser frequency doubling. The polymer was corona poled to induce orientation of the nonlinear chromophores, resulting in a stable poled polymer. End-fire coupling was used to couple the fundamental beam into the polymer channel waveguide. Green light was observed in the form of Cerenkov radiation using a Q-switched Nd-YAG laser lasing at 1064 nm as the fundamental beam. The total efficiency of the second harmonic conversion was 1.4 × 10-3 %/W. © 1995.
