Two-dimensional photonic crystal based sensor for pressure sensing

Abstract

Abstract:In this paper, a two-dimensional photonic crystal (2DPC) based pressure sensor is proposed and designed, and the sensing characteristics such as the sensitivity and dynamic range are analyzed over the range of pressure from 0 GPa to 7 GPa. The sensor is based on 2DPC with the square array of silicon rods surrounded by air. The sensor consists of two photonic crystal quasi waveguides and L3 defect. The L3 defect is placed in between two waveguides and is formed by modifying the radius of three Si rods. It is noticed that through simulation, the resonant wavelength of the sensor is shifted linearly towards the higher wavelength region while increasing the applied pressure level. The achieved sensitivity and dynamic range of the sensor is 2 nm/GPa and 7 Gpa, respectively.

“…2 The PBG consists of a range of frequencies that forbid the propagation of light and are highly sensitive to external conditions, including mechanical stress, 3 temperature, 4,5 electric eld, 6 magnetic eld, 7 chemicals, 8 pressure, 9 and self-organization of multilayered stacks. 10,11 Therefore, PCs are considered the basis for sensing applications, such as a chemical sensors, 12 pressure sensors, 13 and biosensors. 14 Amongst the sensors, biosensors are devices with mechanisms for measuring changes in biological systems.…”

“…Typically, PC is having PBG, which is entirely broken by introducing either line defect or point defect. By breaking the defects, PC based optical devices, such as filter [14,15], directional coupler [16], demultiplexer [17,18], triplexer [19,20], power splitter [21,22], logic gates [23], switches [24,25], electro-optical modulators [26,27], add-drop filter [28,29], and sensors [30][31][32][33][34][35][36][37][38][39][40][41], were reported.…”

“…In the literature, PC/PCRR based sensors were reported for bio sensing applications [30,31], salinity sensor for different temperatures [32], chemical sensor [33], force/strain sensor applications [34,35], pressure sensor [36], biosensor to detect the glucose concentration in urine [5,37,38], aqueous environment [39], breast cancer [40], cancer cell detection [41], pregnancy test, etc. In this paper, a photonic crystal based biosensor is designed, and sensing characteristics such as the Q factor, resonant wavelength, and normalized output power are estimated for albumin, bilirubin, urea, and glucose in urine and also glucose concentration in blood.…”

“…Photonic crystal ring resonator (PCRR) has the advantages of very high sensitivity, small size, high quality factor and very good light confinement (Sharma and Sharan 2015). PCRR-based sensors are used to measure temperature (Zegadi et al 2019;Rajasekar and Robinson 2018), pressure (Rajasekar and Robinson 2018;Krishnan and Robinson 2014), force and strain (Mai et al 2011), biomolecules such as DNA (Hsiao and Lee 2010). Also, determining various components of blood (Sharma and Sharan 2015;Rajendran et al 2018) and determining the concentration of glucose in urine (Robinson and Dhanlaksmi 2016) are other applications.…”
