Programmable Photonic Extreme Learning Machines

Laser &Photonics Reviews, Volume 19, Issue 9, May 6, 2025.
Experimental demonstration of a programmable photonic extreme learning machine using a hexagonal waveguide mesh. Three different classification tasks are solved using the photonic processor. Two approaches based on an evolutionary algorithm and a WDM scheme are proposed to increase the accuracy of the models.
