A 2D photonic crystal based biosensor using rhombic ring resonator is proposed and designed for monitoring the concentrations of glucose. The optical characteristics of rhombic ring resonator is analyzed and predicted by Finite Difference Time Domain method. A new structure of rhombic ring resonator is formed by utilizing bi-periodicity in the design of 2D silicon PC slab in hexagonal lattice with the size of 10 µm and 12µm in X and Z direction, respectively. The sensing parameters are observed in the rhombic ring resonator which are completely depends on the refractive indices of the material used. Thereby the concentrations of glucose can be monitored. The determined sensing parameters such as resonant wavelength is about 1546 nm, quality factor is of 178.5, higher sensitivity of 1000nm/RIU and 100% of transmission efficiency is also achieved.

“…In recent years, all-optical logic gates [8][9][10][11][12] have been reported many configurations such as a Mach-Zehnder interferometer based on self-collimation, periodically poled lithium noibate (PPLN) waveguide, photonic crystal self-collimated beam with a phase lag, semiconductor saturable absorber etalons, nonlinear ring resonators inserted between three parallel line defects, etc. These schemes have some fundamental limitations like latency time, power consumption, speed and size.…”

Abstract:In this paper, a novel all-optical NOR logic gate based on two dimension (2-D) photonic crystals (PC) is designed and simulated by a cascade of two all-optical switches. The new all-optical switch is composed of a nonlinear photonic crystal ring resonator (PCRR) and T-type waveguide. The PC structure has a square lattice of silicon rod with refractive index of 3.39 in air. The bandgap of this structure is derived by the plane wave expansion (PWE) method, which is from a/λ= 0.32 to a/λ= 0.44. In this structure to work at the wavelength of 1550 nm, the lattice constant 'a' should be 630 nm; the total size of the proposed optical NOR gate is only 18 µm × 11 µm. The simulation results using two dimensional finite difference time domain (FDTD) method indicated that the proposed optical NOR logic gate is a potential candidature for ultrafast optical digital circuits.

“…Even for moderate Q factors, cavities have applications such as add/drop filters, minimizing waveguide bending loss and broadband coupling. [3][4][5] In particular a high efficiency broadband coupler could be achieved with a Q-factor of ϳ160. 3 The smallest size cavities in dielectrics are of the order of the cube of the wavelength, which is approximately the size of a unit cell in a PC.…”

The photonic properties of two classes of wavelength-sized cavities are reported for deeply etched InP/InGaAsP/InP planar photonic crystals. The high aspect, deeply etched structures are studied as potential building blocks for nonmembrane type photonic devices in standard InP photonic integrated circuits. The first class consists of cavities of one unit cell in one direction and varying size in the other planar direction. The studied class includes a Fabry-Perot type cavity with one row of missing holes, a simple single missing hole defect cavity, and a cavity consisting of two holes which have been slightly shifted and reduced in hole radius. The best observed quality factor of 65 in this class is obtained for a single hole defect cavity. The second class is comprised of cavities which are derived from a three missing row defect in one direction and varying size in the other direction. This includes a Fabry-Perot type cavity with three rows of missing holes, a point defect cavity consisting of seven unetched holes and a six hole ring cavity. The best observed quality factor of 300 is obtained for the ring cavity in this second class of structures, which is adequate for applications.
