In this paper, we review the progress of optical neural networks. Firstly, based on the principle of artificial neural networks, we elaborate the essence of optical matrix multiplier for linear operation. Then we introduce the optical neural network achieved by free-space optical interconnection and...
an overview of the current status and the latest progress of deep-learning technologies in the field of optical metrology. We first briefly introduce both traditional image-processing algorithms in optical metrology and the basic concepts of deep learning, followed by a comprehensive review of its ap...
low power consumption, and parallel processing, which have the potential to solve the problems of computing capacity and energy consumption. Recently, analog optical computing systems represented by optical neural networks (PNNs) and coherent Ising machines (CIMs) have shown great potential in intellige...
By combining such approaches as hybrid-neural networks, parametric circuits, and data re-uploading we create QML inspired architectures and utilise them for the classification of non-convex 2 and 3-dimensional figures. An extensive benchmarking of our new FULL HYBRID classifiers against existing ...

Solar energy conversion systems are facing the problem of having low optical and thermal performance. The low thermal conductivity of the heat transfer flu... KS Reddy,NR Kamnapure,S Srivastava - International Journal of Low-Carbon Technologies 被引量: 3发表: 2017年 Neural networks supporting audi...
Optical neuron based on VCSEL-SAA VCSEL-SA can be employed as a photonics neuron because it possesses the excitability property behaves analogously to the LIF neuron model. The excitability properties and the spike latency of the VCSELs-SA are shown in Fig. 1[39]. Fig. 1(a) shows that ...
Anthony C Boucouvalas2, Christopher C Davis3, Steve Hranilovic4 and Konstantinos Yiannopoulos5* Abstract This article presents an overview of optical wireless (OW) communication systems that operate both in the short- (personal and indoor systems) and the long-range (outdoor and hybrid) regimes....
Another effective technique in detecting physiological changes is photoplethysmography (PPG). It is an optical method for detecting blood volume changes in the microvascular bed of tissue. It is frequently used to take measurements at the skin’s surface in a non-invasive manner, either by transmitt...
Application areas of optical wireless systems. Full size image Another major application area of OW is in personal communication systems. The rapid progress in optical technology over the past 30 years, driven mainly by fiber-optic systems and display technologies, has enabled the mass production of...
