Study of UV Bleached Channel Waveguide Performance in NLO Polymer Films.
Abstract
We report the studies on UV photo bleached optical channel waveguides in nonlinear optical polymer films. The nonlinear optical polymer used is PMMA/DR1 side chain polymer. Effective indices of the channel waveguides are measured with prism coupling technique along with the effective indices of the bleached and unbleached polymer films. The effective index method was used to predict the effective indices of the channel waveguides from measurements of the slab waveguides without detailed knowledge of the index distributions in the polymer films. Some local effects on the boundaries of the channel waveguides caused by the UV bleaching process are identified with the comparison between direct channel measurement and prediction. It is found that the technique used in this paper can be employed to predict the performance of the channel waveguides processed with proper bleaching process. (MM)
