Nano-Particle Doped Hybrid Organic-Inorganic Photorefractives

POSTER

Abstract

We present results of beam coupling from hybrid photorefractive cells comprising a liquid crystal layer doped with nano-particles of ferroelectric materials adjacent to doped inorganic photorefractive windows. The presence of the nano-particles significantly enhances the optical coupling between the signal beam and pump beam. Full Bragg matched amplification of a signal beam is demonstrated for grating spacings from 5$\mu $m to less than 800nm.
