Photonic liquid crystal fiber intermodal interferometer

Abstract

In this work, we present a novel interferometer based on liquid crystal and photonic crystal fiber technology.The objective of this project is the development of a tunable (switchable) modal (Mach-Zehnder) interferometer for optical communications or sensing.This interferometer has been manufactured splicing a short portion (between 15 and 30 mm) of photonic crystal fiber with two single mode fiber pigtails.The study shows a high sensitivity of the interferometer to the polarization of the launching light..
