Abstract

A method for making a non-linear optical polymer layer. The method includes flash evaporating a liquid polymer precursor mixture containing a plurality of non-linear optical molecules forming an evaporate, cryocondensing the evaporate on a substrate forming a cyrocondensed polymer precursor layer, and crosslinking the cryocondensed polymer precursor layer. The surface may be electrically biased for poling during crosslinking.
