A novel configuration for single-mode all-fiber optic, liquid crystal based intensity modulation is suggested. The electrodes have the form of two thin indium tin oxide films, one of which is directly deposited on top of the polished face of the optical fiber. Intensity modulation using nematic and ferroelectric liquid crystal is demonstrated showing that the device offers the potential for low loss (<0.5 dB), high modulation depth (>20 dB), and moderate drive voltages for frequencies up to several megahertz at 633-nm wavelength.
提出了一种基于液晶的单模全光纤强度调制的新型结构。电极采用两个薄氧化铟锡薄膜的形式，其中一个直接沉积在光纤抛光面的顶部。利用向列型和铁电型液晶进行强度调制的实验得到了验证，结果表明该器件具有低损耗（<0.5 dB）、高调制深度（>20 dB）的潜力，并且在633纳米波长下，对于高达几兆赫兹的频率，所需的驱动电压适中。
