PROJECT TITLE :

Highly Sensitive Plasmonic Photonic Crystal Temperature Sensor Filled With Liquid Crystal

ABSTRACT:

A completely unique highly sensitive surface plasmon resonance-primarily based liquid crystal (LC) photonic crystal fiber (PCF) temperature sensor is presented and studied. Through this letter, the coupling characteristics between the core guided mode inside the PCF core infiltrated with nematic LC and surface plasmon mode on the surface of nano gold wire are studied very well. The structural geometrical parameters of the proposed style, such as range of metal rods, core diameter, and metal rod diameter are optimized to achieve highly temperature sensitivity. The prompt sensor of compact device length of 20 $mu textm$ proved to surpass the recent sensors with high sensitivity of ten nm/°C. The results are calculated using a full-vectorial finite-component method with irregular meshing capabilities and perfectly matched layer boundary conditions.
