All-optical logic gates are indispensable elements in optical devices and optical computing. Our logic gates are based on bidimensional photonic crystals, where the pillars radius and lattice constant are chosen in such a way that the logic gates are actuated at the wavelength of 1550 nm. The contrast ratios for the NOT, XOR, NOR, and XNOR gates are 26.82 dB, 26.77 dB, 8.34 dB, and 20.17 dB respectively. The response time of the different logic gates is approximately 8.5 ps, resulting in a data transmission rate of 0.117 Tb/s. One of the advantages of our study, from the logic gate NOT we could design all the other gates such as XOR, NOR, and XNOR.

“…The novel proposed optical integrated JK flip flop is introduced using a 2-D photonic crystal to use the speed and increase the performance of the optical network, optical memory, and optical CPU [1]. In recent years, many papers have proposed optical digital devices such as logic gates, digital comparator, Decoders, Encoder, Multiplexer, DE multiplexer, half adder, and full adder by using the photonic crystals [10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26], moreover many all optical SR and D flip flops have been proposed [27,28,29]. None of all previous PhC's and optical logic design performs any JK flip flop by using the integrated 2D photonic crystals which is important for optical digital processing.…”

“…An implementation using silicon dielectric with square lattice with a footprint of 45.36 μm 2 attained a CR of 8.29 dB at 1550 nm [26]. A linear structure of footprint 60.2 μm 2 for AO-XOR operation was proposed with a CR of 14.7 dB and low response time [27]. A configurable structure working on interference effect with dimensions of 192 μm 2 was designed to achieve XOR functionality with an extinction ratio (ER) of 23 dB [28].…”

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.
