“…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.

High-sensitivity biosensor for simultaneous detection of cancer and diabetes using photonic crystal microstructure

In this study, we propose 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, and 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 method for samples under study. The diagnosis of three types of cancer and diabetes is based on changing the samples' refractive index by applying the laser source centered at 1550 nm. Our results demonstrate that the proposed structure's quality factor and sensitivity can be adjusted by changing the sensor's geometry. They reveal that the transmission power is between 91% ~ 100%, depending on the sample. The sensitivity range is also between 1294 and 3080 nm/RIU. The maximum figure of merit is about 1550.11 RIU -1 with a detection range of 31×10 -6 RIU. The small biosensor area of 61.56 µm 2 makes it a suitable device for various applications in compact photonic integrated circuits.

“…Every PCRR has a resonant mode, acting as an optical pass-band or stopband lter. So far, a large number of PhC-based devices such as optical lters [20][21][22][23], logic gates [24][25][26], encoders [27,28], comparators [29,30], adders and subtractors [10,31,32], registers [33,34], and memories [35][36][37], as well as all-optical clocked sequential circuits including ip-ops [38,39], synchronous and asynchronous counters [40,41] have been designed and fabricated. New functionality was created using high nonlinear dielectric rods in the resonator, and switching applications can be achieved.…”

In this paper, we report a new design of all-optical full-adder using two nonlinear resonators. The PhCbased full-adder consists of three input ports (A, B, and C for input bits), two nonlinear resonant cavities, several waveguides, and two output ports (for the Sum and Carry). Eight silicon rods and a nonlinear rod composed of doped glass form each resonant cavity. The well-known plane wave expansion technique is used to calculate the photonic band structure. It shows a wide photonic bandgap in the wavelength range of 1365 nm to 2074 nm covering the C and L optical transmission bands. The nite-difference timedomain method is applied to study the light propagation inside the full-adder. Our numerical results demonstrate when the incoming light intensity increases, the nonlinear optical Kerr effect appears and controls the direction of light emitted inside the structure as desired. The maximum time delay and footprint of the proposed full-adder are about 3ps and 758.5 µm 2 , respectively. Therefore, due to the low time delay and small footprint, the presented design can be used as a basic mathematical operator in the all-optical arithmetic logic unit.
