Research Abstract

Studies for developing a new storage-type optical device for telecommunication were performed by employing the thermal recording method for smectic liquid crystals (LCs). Excellent properties such as high attenuation ratio and good polarization-dependent loss (PDL) were achieved by the device. New LC composites with high transition temperatures were synthesized, and their thermal durability was sufficient for practical applications. To prevent unnecessary light transmittance during the thermal process, the light scattering phenomena of nematic LCs was utilized, and a tandem device composed of smectic and nematic LCs was fabricated. This tandem device could be used to develop a new unique storage-type variable optical attenuator (VOA).
