Abstract

We report significant enhancement of second-harmonic-generation intensity in a nonlinear optical polymer by strongly confining the fundamental light in a planar microcavity. Employing a microcavity formed by a distributed Bragg reflector and a silver layer, we have observed up to a factor of 50 increase of second-harmonic light intensity in polymer thin films.
