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).

“…All-optical logic gates are crucial for realizing ultrafast signal processing [1][2][3]. Full-adder is an optical signal process device used in every fundamental mathematical operator [4][5][6][7][8][9]. A full-adder consists of three input ports and two output ports; thus, it can add three binary digits, and two binary digits can be obtained at the output ports called Sum and Carry.…”

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.
