Fully analogue photonic reservoir computer [PDF]
Scientific Reports, 2016 AbstractIntroduced a decade ago, reservoir computing is an efficient approach for signal processing. State of the art capabilities have already been demonstrated with both computer simulations and physical implementations. If photonic reservoir computing appears to be promising a solution for ultrafast nontrivial computing, all the implementations ...

Asynchronous photonic time-delay reservoir computing
Optics Express, 2023 Time-delay reservoir computing uses a nonlinear node associated with a feedback loop to construct a large number of virtual neurons in the neural network. The clock cycle of the computing network is usually synchronous with the delay time of the feedback loop, which substantially constrains the flexibility of hardware implementations.

Neuromorphic Computing Based on Silicon Photonics and Reservoir Computing [PDF]
IEEE Journal of Selected Topics in Quantum Electronics, 2018 We present our latest progress using new neuromorphic paradigms for optical information processing in silicon photonics. We show how passive reservoir computing chips can be used to perform a variety of tasks (bit level tasks, nonlinear dispersion compensation, etc.) at high speeds and low power consumption.

Photonic reservoir computer based on frequency multiplexing
Optics Letters, 2022 Reservoir computing is a brain-inspired approach for information processing, well suited to analog implementations. We report a photonic implementation of a reservoir computer that exploits frequency domain multiplexing to encode neuron states. The system processes 25 comb lines simultaneously (i.e., 25 neurons), at a rate of 20 MHz.
