本文提出了光纤通信用光调制器的简单而新型的结构及其实验,它是使用高分子分散型液晶的。作者采用了在截面上有ITO(钢锡氧化物)透明电极的两个单模光纤之间形成PDLC层的结构,制作出小型而非偏振光依赖的电场控制型光纤调制器。结果,用简单的工艺获得了接近实用水平的超小型光纤调制器,其在1.3μm波长 This paper presents a simple and novel structure and experiment of the optical modulator for optical fiber communication, which uses a polymer dispersed liquid crystal. The authors used a structure in which a PDLC layer was formed between two single-mode optical fibers having an ITO (tin-oxide) transparent electrode in cross-section to produce a small, non-polarization dependent electric field controlled fiber modulator. As a result, near practical levels of subminiature fiber optic modulators have been achieved with simple processes that operate at 1.3 [mu] m wavelength
