Two highly sensitive optical sensor topologies are proposed and simulated in this paper. The proposed structures are optimized to provide better performance characteristics such as sensitivity, detection limit, and quality factor. They are based on two-dimensional photonic crystals consisting of rectangular arrays of GaAs rods in SiO 2 substrates. Such lattices have bandgaps for transverse magnetic modes. Twodimensional finite difference time domain and plane wave expansion methods are used for the simulation and analysis of the refractive index sensors and particle swarm optimization method is used to optimize the structural parameters. The designed structures show a high sensitivity to refractive index variations. They are able to detect refractive indices from 1.33 to 1.5. An excellent figure of merit equal to 737 RIU −1 is observed for the proposed structure and a significant improvement is observed compared to the structures reported in the literature.

“…In order to use them as sensors, it is desirable to have PhC resonators with intense light/matter interaction between analyst and optical fields. These PhC resonators are structures reported by different researchers for detection purposes [11][12][13][14][15][16][17][18]. These resonator structures are most widely used as the ring cavity, which is very sensitive to IR variation and provides better sensitivity compared to other optical devices.…”

A biochip is made from a two-dimensional photonic crystal waveguide and a rhombus shape that acts as a resonator. This biochip is a sensor that can detect different concentrations of glucose with amounts of 10, 20 and 60% in water. Here, we studied and simulated the concentrations of glucose, which have a refractive index n of 1.3477, 1.3635 and 1.4394, respectively. To identify these quantities, we have proposed a square lattice structure formed by silicon rods with a n = 3.46. With the help of these dielectric rods immersed in the air, it was possible to analyze the detection characteristics. Our results are examined according to COMSOL software by using the PWE method and the finite element method in order to have the PBG and which helped us to create the structure and extract the propagation at resonance, the field norm, the total energy density (TED), the power flow norm (PFN), the transmission and the sensitivity. The concentrations of glucose in water answered yes to the variations for each of the E-field, the TED, the PFN and the sensitivity. These variations are due to the radius r and refractive index n of each concentration used. This structure can help with diabetes self-monitoring.

The paper illustrates a photonic crystal micro ring resonator based pressure sensor utilizing the variation of refractive index of the material and the structural deformation. FEM is employed for reformed structure analysis. Structural deformation and change in refractive index are taken as input variables in FDTD simulation and the external pressure is measured by analyzing shift in resonance wavelength. A comparative study of the rod type and the hole type photonic crystal micro ring resonator based pressure sensor is reported in this paper. Both the structures are ultra compact and can be used for compact photonic integrated circuits.dynamic range, FDTD, FEM, micro ring resonator, photonic crystal, pressure sensor | INTRODUCTIONPhotonic crystals (PhC) are artificially created periodic microstructure of two dielectric materials of different refractive indices (RI). This type of periodic arrangement creates a photonic band gap (PBG) through which electromagnetic waves of a range of particular wavelength are restricted to propagate. 1 The wide constitutional specifications range in the PhC provides the flexibility to control the properties of PhC based devices. [2][3][4][5] Thus the manipulation of the electromagnetic waves is possible in the PhC based devices by the use of different dielectric materials and by varying the geometrical parameters like the lattice distance of crystal structure and the radius of the rods of the PhCs. This unique property of the PhCs has opened up a new window in the area of photonic sensors. PhC based structures have numerous applications in the designing of logic and arithmetic operations. Recently M. Mohammadi et al. published an article on the design and simulation of a half adder based on grapheme ring resonators. The output spectrum of the model was analyzed using Finite-difference-timedomain (FDTD) and coupled-mode theory (CMT) method. 6 PhC based cascaded ring resonator structures are also used by different researchers to design different multiplexer and demultiplexer circuits. [7][8][9] Among the two approaches, used for the sensing purposes based on PhC namely the intensity variation and the spectrum analysis, the later one is usually preferred because of its higher sensitivity. 10 Recently, new fields of research Uttara Biswas, Bhuvneshwer Suthar, Deepak Kumar, and Chittaranjan Nayak contributed equally to this work.
