“…Photonic crystals can confine light better than other optical structures, and this is one of the suitable properties for making photonic crystal sensors. It is one of the photonic crystal structures in the design of biosensors such as blood component detection sensors that can detect blood parameters [24][25][26][27][28][29][30][31][32][33]. Another biosensor created with a photonic crystal structure is the detection of different types of cancer cells [34][35][36] and potential malaria detection [37][38][39][40][41].…”

The cholesterol detection of human blood using a two-dimensional photonic crystal biosensor has been studied in this paper. The structure calculations are done using Plane Wave Expansion (PWE) and Finite Difference Time Domain (FDTD). Photonic crystals can be used to detect biological components by utilizing a two-dimensional structure and resonator nano ring. These nano rings cause waveguide and resonator coupling. The cylinders around the sensing region have investigated the improvement structure output. The quality factor and figure of merit (FOM) for this sensor are 4988 and 57.14 RIU−1, respectively, and the low detection limit (DL) is 0.001(RIU), with a sensitivity of 32 (nm/RIU).

Optical encoder is playing an essential starring role in optical communication and computing applications. This paper presents a new structure for 4 x 2 optical encoder based on Two Dimensional Photonic Crystals (2DPC). The proposed structure consists of silicon rods in background of air using hexagonal lattice. The proposed structure is composed of four input waveguides and two outputs. The band structure is examined by Plane Wave Expansion (PWE) method and the performance parameters of the 4x2 encoder, namely, normalized output power, footprint, contrast ratio, response time and bit rate are analyzed using Finite Difference Time Domain (FDTD) method. The proposed encoder is operated at 1550nm. The low response time, and small footprint have shown that the encoder is exceptionally suitable for high performance optical networks and photonic computational integrated devices.

in this paper, we present a design of a two-dimensional photonic crystal-based temperature sensor (PhCs_2D). It is designed to detect temperature based on the effective modulation of the refractive index of silicon (n_Si). This temperature is monitored by the sensor for values ranging from T = 0°C to °T = 68°C. To analyze the detection principle, this two-dimensional square lattice structure is based on a Photonic Crystal Ring Resonator with a Swiss Cross in the middle (PCRR). The resonator is wedged between two parallel waveguides in a square lattice based on silicon rods immersed in the air, hence the refractive index equal to 3.46. This resonator has been studied as a promising solution due to the deformation, the extreme sensitivity as well as the variation of the position of the rods or cavities within the PhC resonators. It plays a relevant role in the detection of different temperature levels (T) over a wide dynamic range. We investigate the propagation and transmission of this structure that opens an optical channel drop filter (CDF) and the study is extended for tuning the channel filter (CDF) wavelength with temperature. The band diagram is analyzed and the transmission characteristics are obtained using plane wave expansion (PWE) and finite element method (F.E.M) respectively. This method evaluates the functional parameters of the sensor such as: resonance wavelength (λ_res), quality factor (Q), dynamic range, transmission efficiency and sensitivity (S). Our results show a resonance wavelength shift of the PCRR that increases linearly with increasing temperature. In this work, shift is used for sensor application. By F.E.M simulation under COMSOL software, we were able to obtain a resonance wavelength at 1640nm, a quality factor at 410 and a sensitivity of 370.6 pm/℃. The exceptional sensing capability makes PhC resonators a promising opto-mechanical sensing element to be integrated into various transducers for temperature sensing applications.
