Paper Abstract

In this paper, we present a long-period fiber grating (LPFG) with a unique liquid crystal (LC) cladding. The experimental study is focused on achieving external tuning by applying electric fields to influence the spectral properties of LPFGs using LCs for potential applications in photonic sensing and in communications. The LPFGs are fabricated in two types of fibers: single-mode (SM) fiber and photonic crystal fiber (PCF). Their sensitivities when surrounded by nematic LCs mixtures are compared. In addition, the influence of an external electric field on the spectral properties of LPFGs with an "active" LC medium is investigated. We demonstrate a spectral shift, under an external electric field, in the transmission spectrum of the LPFG based on SM fiber with 1294-1b LC mixture serving as the surrounding medium.
