Paper Abstract

This work presents an investigation focused on the advanced tunable photonic components known as liquid crystal longperiod fiber gratings (LC-LPFGs). It is demonstrated that by coating the LPFGs with a thin low-birefringence 1800b LC layer the thermal sensitivity of the attenuation band can be significantly reduced. Moreover, for the LPFGs coated with a thin medium-birefringence 1702 LC layer, a fast and repeatable electrical switching of the attenuation band can be achieved.
