Abstract

A new chromopore, named HR-2-54, was designed as a doping agent for developing new photorefractive polymer composites. As observed by frequency-dependent ellipsometry, the chromopore has a strong polarizability anisotropy that can lead to high efficiency in low T_s polymers. Four wave mixing experiments on a HR-2-54:PVK:ECZ:TNF samples demonstrated a four-fold improvement in refractive index modulation compared with previous polymers, while asymmetric two-beam coupling experiments confirm the photorefractive nature of these highly efficient gratings. Samples with 40% chromopore loading showed excellent stability. Maximum diffraction could be observed at 830 nm in 105 μm-thick samples of HR-2-54:PVK:ECZ:TNFDM at an applied field of 50 V/μM.
