Abstract

Electrical modulation of an etched long-period fiber grating (LPFG) using a liquid crystal (LC) cladding with improved controllability and stability were presented. The diameter of the optical fiber was reduced to 50 μm by means of chemical etching. The cladding modes were found to undergo Fresnel reflection resulting in propagation loss. Electrical modulation of the coupling strength between the core and leaky cladding modes was possible with the help of surrounding nematic director of the LC. The LC-cladding LPFG also found an application as polarization-dependent loss (PDL) compensator owing to its sensitivity to polarization state of light wave.
