“…The operation depends on the incident of light in a plan wave that can propagate along specific direction through a structure by using total internal reflection (TIR) phenomena. The (TIR) happens when the angle of incidence is greater than the critical angle [76].…”

In this paper, different topologies were discussed and their effect on the design of photonic crystal applications was evaluated. They can be classified into four categories (i.e., ring resonator, selfcollimation, waveguide, and cavity-based structures). The figure of merits of each topology and its impact on design modules were explained and compared for two different applications (i.e., half-adder and decoder). Finite difference time domain (FDTD) and plane wave expansion methods are the two numerical approaches that were used to analyze the proposed designs. The truth table for each application was introduced. Comparison tables were organized to discriminate the valued characteristics for each structure. Based on the extracted tables, the appropriate topology can be chosen for the required design application according to the needed characteristic.

“…Currently, photonic crystal platforms are gaining a lot of attention owing to their fascinating features like high integration capability with existing electro-optic as well as optical integrated circuits, flexibility in design, ultra-compact dimensions, wide operating bandwidth, high speed and low power consumption [19]. Photonic crystals possess a unique feature called bandgap which enable efficient manipulation of light in the required direction over a wide operating bandwidth [20]. Photonic crystal-based logic gates usually operate on the principles of self-collimation, Kerr non-linear effect or linear interference effect.…”

In this work, an optimized structure of an XOR gate working in the optical domain is put for-ward to achieve high contrast ratio and extremely compact dimensions using a photonic crystal platform. The above structure employs silicon rods in a hexagonal lattice configuration. The design works purely on linear interference effect between the incoming light signals and does not involve any non-linear materials. The Finite Difference Time Domain based simulations are utilized to study the propagation of light within the structure and the Plane Wave Expansion Method is applied to generate bandgap structure. After optimization of the various design parameters, a contrast ratio of 31.76 dB is attained by the proposed structure along with a response time of 0.46 ps and a footprint of 42.24 μm 2 . The device can be operated in the C Band with optimum performance at 1550 nm, which is the telecommunication wavelength. The operating bit rate for the proposed structure is 2.17 Tbps. All-optical XOR gate being a universal gate forms the building blocks of various sequential and combinational logic designs suitable for optical computing and communication applications.

“…Due to its specific features in controlling the propagation of optical signals, PhCs received considerable attention from researchers [9,10]. Among the methods suggested, we can divide into four categories: selfcollimated beam, nonlinear Kerr material-based gates, multi-mode interference, and interference-based defect method [11]. So far, a lot of effort has been made to design all-optical logic gates [12][13][14][15][16][17][18][19][20][21], while few studies focused on the development of multifunctional structures.…”

In this paper, we are going to propose a novel structure of all-optical NOT, XOR and XNOR logic gates are presented using a two-dimensional photonic crystal (2D-PhC). This structure is optimized by varying the radius of the cavity, to obtain a quality factor Q = 1192, and also has several ports of entry and one port of output. The size of each structure is equal to 85.8 μm2. The contrast ratios for the structures proposed all-optical NOT, XOR and XNOR logic gates between levels “0” and “1” are, respectively, 25.08, 25.03, and 14.47 dB. The response time for the three logical gates is 8.33 ps, and the bit rate is calculated at about 0.12 Tbit/s, all simulations are based on both numerical methods such as finite difference time domain (FDTD) and plane wave expansion (PWE). Designed logic gates are characterized by low power consumption, compactness and easy integration.
