“…PhCs are designed in one, two, and three-dimensional (3D) structures, whose two-dimensional (2D) structure has been considered by researchers due to its greater applications and fabrication simplicity. Research groups designed a variety of structures using two-dimensional PhCs such as optical filters [25][26][27][28][29][30][31][32], Full adders [33][34][35], encoders [36], comparators [37,38], Flip-Flop [39], analog-to-digital converters [40,41], registers [42,43], memories [44][45][46], sensors [47,48], Biosensors [49,50]. Photon crystals are designed in one-dimensional (1D), 2D and 3D, which is a proposed structure in the present research according to the 2D PhCs.…”

This study proposes a refractive index sensor for the simultaneous detection of cancer and diabetes based on photonic crystals (PhC). The proposed PhC composed of silicon rods in the air bed arranged in a hexagonal lattice forms the fundamental structure. Two tubes are used to place the cancerous or diabetic samples for measurement. The sensor’s transmission characteristics are simulated and analyzed by solving Maxwell’s electromagnetic equations using the finite-difference time-domain approach for samples being studied. Therefore, diabetes and cancer are detected according to the changes in the refractive index of the samples using the laser source centered at 1550 nm. Considering the findings, the sensor’s geometry changes to adjust the suggested sensitivity and quality factor of structure. According to the results, transmission power ranges between 91 and 100% based on the sample. Moreover, sensitivity ranges from 1294 to 3080 nm/RIU and the maximum Figure of Mertie is nearly FOM = 1550.11 ± 150.11 RIU−1 with the detection in range 31 × 10−6 RIU. In addition, the small area (61.56 μm2) of biosensor results in its appropriateness for different uses in compact photonic integrated circuits. Next, we changed the shape of the dielectric rods and investigated their effects on the sensitivity parameter. The sensitivity and figure of merit after changes in the shape of dielectric rods and nanocavities are at best S = 20,393 nm/RIU and FOM = 9104.017 ± 606.93 RIU−1, receptively. In addition, the resolution detection range is 203.93 × 10−6 RIU.

A surface plasmon resonance (SPR) sensor based on photonic crystal fiber (PCF) was designed and gold metal was used as a sensitive plasmonic layer. Performance of this sensor was investigated using the finite element method (FEM) for refractive indexes (RI) of 1.33 to 1.41. This sensor has a sensitivity for the defined refractive indexes range between 2600 to 28921 nm/RIU at wavelengths of 650 to 1400 nm and has the highest resolution and best FOM with a value of 3.46×10 -6 RIU, 222.45 RIU -1 , respectively. Diagnosis of cancer by examining blood samples is one of the advantages of this sensor. Due to the simple structure of this sensor and its good performance, it can be used as a good diagnostic tool for analytes with different refractive index.
