Abstract
Device for doubling the frequency of a light wave, comprising a non-linear optical medium of an oriented synthetic resin composition for guiding a fundamental light wave, while forming a second harmonic wave, which medium is composed of a waveguide having a spatially periodic structure for phase matching. The oriented synthetic resin composition exhibits alternate regions having a mutually different second order (non-linear optical) susceptibility. Said structure can be manufactured in an efficient manner by exposing the synthetic resin composition to patterned radiation.
