“…Furthermore, SOA can be combined with other interferometric configurations including Michelson interferometers (MI) 43 , ultrafast nonlinear interferometers (UNI) [96][97][98]49 and delayed interferometers (DI) 99−103 . Compared with the SOA architecture, SOA-assisted interferometer architecture is generally more suitable for integration but its stability is poor and it is affected by additional noise 20 .…”

Optical computing and optical neural network have gained increasing attention in recent years because of their potential advantages of parallel processing at the speed of light and low power consumption by comparison with electronic computing. The optical implementation of the fundamental building blocks of a digital computer, i.e. logic gates, has been investigated extensively in the past few decades. Optical logic gate computing is an alternative approach to various analogue optical computing architectures. In this paper, the latest development of optical logic gate computing with different kinds of implementations is reviewed. Firstly, the basic concepts of analogue and digital computing with logic gates in the electronic and optical domains are introduced. And then a comprehensive summary of various optical logic gate schemes including spatial encoding of light field, semiconductor optical amplifiers (SOA), highly nonlinear fiber (HNLF), microscale and nanoscale waveguides, and photonic crystal structures is presented. To conclude, the formidable challenges in developing practical all-optical logic gates are analyzed and the prospects of the future are discussed.

“…These nonlinear effects make the SOA an attractive device for applications in optical networks in terms of low power consumption, small footprint, and higher optical integration. Among these nonlinear effects are the cross-gain modulation (XGM), cross-phase modulation (XPM) and four-wave mixing [28][29][30][31].…”

The physical layer of an optical network is vulnerable towards various types of security threats such as physical infrastructure attacks and eavesdropping, where the security item requires more attention in front of the dramatically grows in network capacity. In this paper, authors propose a comparison in performance of zero correlation zone-Optical Code Division Multiple Access based on different confidentiality mechanisms implemented using existing optical logic components such as line selectors, wavelength convertors and XOR gates. The performance of the proposed designs in terms of log of the bit error rate (BER) as function of the received power was evaluated through OptiSystem software simulation. The achieved results demonstrate that design 3 is the best confidentiality solution in terms of received power, BER performance and architecture complexity.

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.
