Description
Summary:•Thermo-optical response of highly birefringent photonic crystal fiber infiltrated with ethanol, is numerically analyzed.•Results shows a linear dependence between the PCF birefringence and the temperature.•The sensitivity S can easily reach 7,51×10−6 order of magnitude by Celsius degree.•In comparison with other temperature sensor based on birefringent Photonic crystal fiber, our designed sensor has higher sensitivity. In the present paper, we propose and investigate theoretically by full vector finite element method a novel temperature sensor, based on highly birefringent photonic crystal fiber infiltrated with ethanol along the fiber length. Simulation results show a linear dependence of the fiber birefringence with temperature. Birefringence is an increasing function of temperature, and the temperature sensitivity coefficient can reach 7,51×10−6 by Celsius degree. In comparison with other temperature sensors based on birefringent photonic crystal fibers, our designed sensor presents a higher sensitivity.
