A novel proposal for all optical 2 × 4 decoder based on photonic crystal and threshold switching method

A novel design of an all‐optical D flip‐flop based on 2D photonic crystals

“…In the field of Sequential circuits, such as flip Flops, there has been very little work done that has disadvantages, such as dimensions and complexity, that have been tried to eliminate in this paper. [15][16][17][18][19][20][21][22][23][24][25][26][27] Light waves of specific frequencies cannot pass through photonic crystals because of their alternating dielectric structures. There is a term for the frequency range in which light cannot pass through a structure, known as the photonic band gap (PBG).…”

“…Photonic crystals have been used to design combined logic circuit types such as adders, subtractors, coders, decoders, multiplexers, and de‐multiplexers. In the field of Sequential circuits, such as flip Flops, there has been very little work done that has disadvantages, such as dimensions and complexity, that have been tried to eliminate in this paper 15–27 …”

Design of Integrated All Optical JK Flip Flop using 2D Photonic Crystals

“…All optical logic devices based on the Photonic crystals (PhC) are considered as main devices to handle a large bandwidth signal at very high speed in present all optical signal processing systems and the future optical networks [1,2]. Consequently, it is necessary to move towards all optical processing units, to overcome the electronic bottlenecks speed and fully exploit the advantages of optical fibre communication system and photonics crystals, where the data will remain in the optical without optical to electrical conversion and vice versa [1][2][3]. The optical flip flop can be used to perform a fast central Processing unit (CPU) and optical memory using optical hardware components [4][5][6] such as the photonics crystals.…”
