“…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.…”

Photonic sensing technology is a new and accurate measurement technology for bio-sensing applications. In this paper, a two-dimensional photonic crystal ring resonator based sensor is proposed and designed to detect the glucose concentration in urine over the range of 0 gm/dl-15 gm/dl. The proposed sensor is consisted of two inverted "L" waveguides and a ring resonator. If the glucose concentration in urine is varied, the refractive index of the urine is varied, which in turn the output response of sensor will be varied. By having the aforementioned principle, the glucose concentration in urine, glucose concentration in blood, albumin, urea, and bilirubin concentration in urine are predicted. The size of the proposed sensor is about 11.4 m×11.4 m, and the sensor can predict the result very accurately without any delay, hence, this attempt could be implemented for medical applications.

A 2D photonic crystal based biosensor using rhombic ring resonator is proposed and designed for monitoring the concentrations of glucose. The optical characteristics of rhombic ring resonator is analyzed and predicted by Finite Difference Time Domain method. A new structure of rhombic ring resonator is formed by utilizing bi-periodicity in the design of 2D silicon PC slab in hexagonal lattice with the size of 10 µm and 12µm in X and Z direction, respectively. The sensing parameters are observed in the rhombic ring resonator which are completely depends on the refractive indices of the material used. Thereby the concentrations of glucose can be monitored. The determined sensing parameters such as resonant wavelength is about 1546 nm, quality factor is of 178.5, higher sensitivity of 1000nm/RIU and 100% of transmission efficiency is also achieved.

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.
