In the present work, finite element method (FEM) was used to evaluate the transmission of the suggested 1D PhC thermal sensor. The effect of the inserted nematic liquid crystal (NLC) and the temperature have been studied and analyzed. Here a simulation is considered for NLC (MLC-9200-100) as a thermal sensor. The concept of temperature-dependent thermal sensor application of photonic crystal is presented and studied in both TE and TM modes of the incident beam. The sensitivity, quality factor, and crosstalk of the suggested 1D PhC thermal sensor are evaluated at different values of liquid crystal thickness d(LC).enUniversity for October University for Photonic crystalsBandgapLiquid crystalFinite element methodTransmissionThermal sensorREFRACTIVE-INDEXESBAND-GAPSILICONTRANSPARENTSIArticlehttps://doi.org/10.1016/j.ijleo.2018.05.117
