“…The architecture in 2D PhC presents a self-collimated beam and the splitting phenomena. 23 The model was built out of Si (n ¼ 3.52) rods arranged in a triangular diamond lattice in an air background. By adjusting the faulty hole width to 0.286a and the adjacent hole zone circumference to 0.35a, two line defects were generated in the x direction in the basic techniques.…”

Nowadays, communication has grown into a key area with a rapidly growing user community. The existing broadband users are overcrowded, and its faster speed has now become an essential parameter to meet the consumer's expectations in the growing technology. As a result of our growth in computer technologies, high-speed processors are necessary, which provide simultaneous data computing with lower costs and a performance of more than 10,000 times quicker than electrical computers. Optics has become a more feasible alternative to electronics because of its greater speed. In this study, various methods of photonic crystals (PhCs) have been thoroughly examined, with essential properties and their benefits explained over previously identified methods (semiconductor optical amplifier and nonlinear waveguides) utilized to construct all-optical logic circuits. Particularly, evaluated a number of articles that covered topics including self-collimation effects, PhC waveguide intersection, and multi-mode interference with nonlinear effects. The merits and demerits of each technology are analyzed. Finally, concluded the major difficulties and the potential usage of every method. PhCs are used in logic circuits and devices for high data transmission. The performances of different types of logic gates based on PhC are studied.

The research carried out in the field of optics and photonics with an idea to design and develop the all optical logic devices in the fascinating material known as photonic crystals (PhCs). The structural investigation reveals that the two dimensional (2-D) PhCs is more suitable for fabrication of optoelectronic components. In this article we have designed basic logic gates in 2-D PhCs as they are the building blocks for the construction of optical devices and in these, refractive index is periodically modulated with the wavelength. The understanding of light behaviour in complex PhCs helps in creating photonic band gap (PBG) that can prevent light of certain wavelength propagating in crystal lattice structure. For the selected geometry structure, three PBG bands will exists out of which two of them are transverse electric (TE) and one is transverse magnetic (TM) mode. The PBG bands in the TE mode ranges from 0.31( a λ ) to 0.46( a λ ), 0.61( a λ ) to 0.63( a λ ) and TM mode ranges from 0.86( a λ ) to 0.93( a λ ). The free space wavelength of 1550 nm is set for the finite difference time domain (FDTD) simulation of the structure. The response time and computational overhead required for the proposed OR gate is 0.128ps and 4.4MB is obtained. Also we calculated the extinction ratio for AND gate and NOT gate as 6.19 dB and 10.21 dB respectively.
