Abstract

The preliminary results of the characterization of nematic liquid crystal coated photonic crystal fiber (PCF) interferometers are presented in this paper. Two types of interferometer were fabricated; one by sandwiching a small section of PCF between standard single mode fibers and the second one is formed by tapering a small section of a PCF by collapsing the air holes, and thinning down the air hole collapsed region to a micron size. The interferometers are fabricated from different types of the photonic crystal fiber and temperature studies are carried out to select an interferometer to be coated with the liquid crystal material. The requirement for a suitable liquid crystal materials to be used for PCF interferometers are also discussed. The behaviour of liquid crystal (LC) coated interferometers with temperature and applied electric field is studied to determine the feasibility of using such interferometers in sensing applications.
