Impact of input mask signals on delay-based photonic reservoir computing with semiconductor lasers

2018 · Optics Express

We experimentally investigate delay-based photonic reservoir computing using semiconductor lasers with optical feedback and injection. We apply different types of temporal mask signals, such as digital, chaos, and colored-noise mask signals, as the weights between …

Photonic Decision Making for Solving Bandit Problem Using Laser Network

2022 · 2022 27th OptoElectronics and Communications Conference (OECC) and 2022 International Conference on Photonics in Switching and Computing (PSC)

We propose a scheme of photonic decision making for solving the multi-armed bandit problem using semiconductor laser network as photonic accelerators. We numerically demonstrate that we can solve different bandit problems using the proposed scheme.
