dc.description.abstractIn this work an optical sensors has been designed and studied with different parameters to select the best result of Q factor and sensitivity; for that, we choose a 2D photonic crystal (PhC). The refractive index (RI) sensor is formed by a pointdefect resonant cavity in the quasi-sandwiched waveguide with a hexagonal lattice of air holes. The properties of the sensor are simulated using a couple of two methods finite-difference timedomain method (FDTD) and the plane wave method (PWE). The calculation results show that a change in ambient RI is apparent; the sensitivity of the sensor is achieved. The objective of our research was primarily modeling and optimization geometry of a first coupling path between a waveguide and a ring resonator with base of photonic crystals in order to improve the coupling properties in this structure. It is in this context that we have exploited all the parameters already developed for improve the biodetection properties in a photonic crystal-based structure. The role of our design is to sens small RI changes for detecting glucose concentration using resonant microcavity (RMC).
