Design and Simulation of a New Highly Sensitive Gas Sensor Based on Negative Refraction Photonic Crystal
In this paper, design and simulation of a new highly sensitive gas sensor based on a hybrid photonic crystal (PC) structure, containing negative and positive refractive index sections, is presented. It has been shown that using a PC with negative refraction in the first section, the transmitted power is concentrated on the entrance of the sensing channel, and the transmission of the proposed se...
متن کاملDesign and simulation of a highly sensitive photonic crystal temperature sensor based on a cavity filled with the distilled water
In this paper design and two dimensional (2D) simulation of a photonic crystal highly sensitive temperature sensor is presented. The 2D simulations are based on finite-difference time-domain (FDTD) method and are done using Rsoft software. The device is constructed using a cavity filled with the distilled water located in the center of the photonic crystal waveguide. The operation of the propos...
متن کاملTemperature Tunability of Dielectric/ Liquid Crystal / Dielectric Photonic Crystal Structures
Recently, photonic crystals doped with liquid crystal (LC) material havegained much research interest. In this article new ternary one-dimensional photoniccrystal introduced and studied. The liquid crystal layer of 5CB and 5PCH is sandwichedby two dielectric layers. For the first time, we use four structures SiO2/UCF35/CaF2,SiO2/5CB/CaF2, NFK51/UCF35/NPSK53 and NFK51/5CB/NPSK53. The effect ofte...
متن کاملAnalysis of rectangular ring resonator sensor with photonic crystal microcavity
In this paper, we propose a novel sensor structure based on the rectangular ring resonator with the photonic crystal microcavity (PCM), and optimize the structure using finite-difference time-domain (FDTD) method. This sensor consists of the rectangular resonator with total internal reflection mirror and the PCM, which can be placed at the nearby optical waveguide of the rectangular ring resona...
متن کاملUltra-high sensitivity optical stress sensor based on double-layered photonic crystal microcavity.
In this report, we present the design principles to achieve a highly sensitive optical stress sensor. The structure we use is a double-layered (DL) photonic molecule with optical bonding and anti-bonding states based on whispering-gallery mode in photonic crystal microcavity. By applying finite-difference time-domain and finite-element methods, we simulate the change of optical properties (incl...
