Abstract

Two-dimensional Resonant Waveguide Crossed Gratings (RWCG) were fabricated on azobenzene molecular glass thin films and their resonance behavior was studied once placed in between orthogonally aligned polarizers. Normally-incident polychromatic light was transmitted and/or reflected from these RWCGs only in narrow positive peaks. In addition, the central wavelength and transmitted intensity of these positive peaks were actively modulated by an external light source. Furthermore, a dynamic volume birefringence behavior related to the photomechanical effect of the azobenzene chromophores was observed. A mechanism to explain the polarization conversion of the resonant light using RWCGs at normal incidence was also proposed.
用于波长选择偏振转换和光调制的动态谐振波导交叉光栅
在偶氮苯分子玻璃薄膜上制备了二维共振波导交叉光栅(RWCG),并对其放置在正交排列的偏振片之间的共振行为进行了研究。正常入射的多色光仅在狭窄的正峰中从这些rwcg传输和/或反射。此外,这些正峰的中心波长和透射强度被外部光源主动调制。此外,还观察到偶氮苯发色团的动态体积双折射行为。提出了一种解释正入射RWCGs共振光偏振转换的机制。
