Single-shot optical neural network. [PDF]
Sci Adv, 2023 Analog optical and electronic hardware has emerged as a promising alternative to digital electronics to improve the efficiency of deep neural networks (DNNs). However, previous work has been limited in scalability (input vector lengthK≈ 100 elements) or has required nonstandard DNN models and retraining, hindering widespread adoption.

Optical implementation of the Kak neural network [PDF]
Information Sciences, 2005 We show that the Kak neural network is suitable for optical implementation using a bipolar matrix vector multiplier. We demonstrate how the CC4 algorithm, with suitable modifications to the structure and training algorithm, may be used to build an optical neural network implementing N-Parity.

Optical neural networks: The 3D connection [PDF]
Photoniques, 2020 We motivate a canonical strategy for integrating photonic neural networks (NN) by leveraging 3D printing. Our belief is that a NN’s parallel and dense connectivity is not scalable without 3D integration. 3D additive fabrication complemented with photonic signal transduction can dramatically augment the current capabilities of 2D CMOS and integrated ...

Optical Axons for Electro-Optical Neural Networks [PDF]
Sensors, 2020 Recently, neuromorphic sensors, which convert analogue signals to spiking frequencies, have been reported for neurorobotics. In bio-inspired systems these sensors are connected to the main neural unit to perform post-processing of the sensor data. The performance of spiking neural networks has been improved using optical synapses, which offer parallel ...

Adversarial Attacks on an Optical Neural Network
IEEE Journal of Selected Topics in Quantum Electronics, 2023 Adversarial attacks have been extensively investigated for machine learning systems including deep learning in the digital domain. However, the adversarial attacks on optical neural networks (ONN) have been seldom considered previously. In this work, we first construct an accurate image classifier with an ONN using a mesh of interconnected Mach-Zehnder

Optical Soliton Neural Networks
, 2023 The chapter describes the realization of photonic integrated circuits based on photorefractive solitonic waveguides. In particular, it has been shown that X-junctions formed by soliton waveguides can learn information by switching their state. X junctions can perform both supervised and unsupervised learning.
