Abstract

The classical and the nano-structured spatial light modulators (SLMs) especially based on the polyimide photosensitive layers, as the key element of the optoelectronic devices, display, and telecommunications schemes are considered. The main emphasis is placed on the device with a polyimide photo-layer due to its high sensitivity and acceptable performance. A modulator’s basic characteristics are studied taken into account the comparison with the different types of the photo-layers, such as: ZnSe, ZnS, a-Si:H. Liquid crystal (LC) media is considered as the modulation system. It is indicated that the different methods and approaches are applied for investigation of the basic SLM parameters, such as: Z-scanning technique, third harmonic generation, four-wave mixing set-up, etc. In the current paper the laser holographic technique is used to investigate the resolution, sensitivity, and speed of the LC-SLM devices. The influence of the fullerene doping on the organic photo-layers based on the polyimide materials is presented. This influence of this nano-structuration process on the modulator’s basic parameters is discussed.
纳米结构对聚酰亚胺基空间光调制器参数的影响
研究考虑了传统的和纳米结构的空间光调制器(SLMs),特别是基于聚酰亚胺光敏层的空间光调制器(SLMs),它们是光电设备、显示器和电信方案的关键元件。由于聚酰亚胺光敏层具有高灵敏度和可接受的性能,因此主要重点放在具有聚酰亚胺光敏层的设备上。在研究调制器的基本特性时,考虑到了与不同类型光层的比较,如ZnSe、ZnS、a-Si:H。液晶(LC)介质被视为调制系统。研究表明,在研究 SLM 基本参数时采用了不同的方法和途径,例如:Z 扫描技术、三次谐波技术:Z 扫描技术、三次谐波生成、四波混合设置等。本文采用激光全息技术来研究 LC-SLM 设备的分辨率、灵敏度和速度。本文介绍了富勒烯掺杂对基于聚酰亚胺材料的有机光分层的影响。讨论了这种纳米结构工艺对调制器基本参数的影响。
