Abstract Photonic neural networks are brain-inspired information processing technology using photons instead of electrons to perform artificial intelligence (AI) tasks. However, existing architectures designed for a single task but fail multiplex different tasks in parallel within monolithic system due the competition that deteriorates model performance. This paper proposes novel optical multit...

Transport networks form the backbone of communication networks by cost-efficiently offering huge bandwidth and by guaranteeing a high service quality and availability. These requirements can best be met by using optical communication technologies. Currently, wavelength-switching is the most prominent network technology employing optical fiber communication and wavelength division multiplexing. ...

The multi-log2N network architecture is attractive for constructing optical switches, and the related routing algorithms are critical for the operation and efficiency of such switches. Although several routing algorithms have been proposed for multi-log2N networks, a full performance comparison among them has not been published up to now. Thus, we rectify this omission by providing such a compa...

Multi-touch interaction with computationally enhanced surfaces has received considerable recent attention. Approaches to the implementation of multi-touch interaction such as Frustrated Total Internal Reflection (FTIR) and Diffused Illumination (DI) have allowed for the low cost development of such surfaces, leading to a number of technology and application innovations. Although many of these t...

The topological charge of an optical vortex is a quantity rather stable against phase distortions, for example, turbulence. This makes the attractive communications, but many structured beams it unknown. Here, we derive (TC) coaxial superposition spatially coherent Laguerre–Gaussian with different colors, each beam its own wavelength and TC. It turns out that TC such equals LG longer wavelength...

Abstract Developing strategies to effectively discriminate between different quantum states is a fundamental issue in information and communication. The actual realization of generally optimal protocols this task often limited by the need supplemental resources very complex receivers. We have experimentally implemented two discrimination schemes minimum-error scenario based on receiver featured...

Wireless optical is categorized as a last mile solution for the sake of complementing the Gigabits network solution. Recently, multi-channels wireless optical (WO) has been introduced to increase the coverage and the link range up to kilometers and reduce other possible losses. This paper proposed a multi-channels ellipsoid structure by analyzing a transmission distance by incorporating the num...

This paper provides a survey on existing survivability related problems and include the new algorithm based on existing algorithms. Survivability has become an important issue and topical subject in WDM networks. This paper reviewed the literature on survivability against multi-domain or link failures to ensure reliability in WDM networks. Survivability in multi-domain optical networks is very ...
