Light modulation in elliptical-core liquid crystal fibers

An original idea of external parameters (electric field, temperature, press ure etc.) monitoring is presented. After the theoretical analysis of the li ght modulation in a liquid crystal and elliptical-core anisotropic fiber th e latest experimental results are reported. Due to measurands-induced chang es in birefringence and propagation conditions the liquid crystal and ellip tical-core fiber uniting unique advantages of liquid crystals and quality o f fiber technology acts as a sensing medium and can be used for continuous monitoring of different external parameters.
