Limitations of the recall capabilities in delay-based reservoir computing systems

Köster, Felix ; Ehlert, Dominik ; Lüdge, Kathy (2020-10-02)

We analyse the memory capacity of a delay-based reservoir computer with a Hopf normal form as nonlinearity and numerically compute the linear as well as the higher order recall capabilities. A possible physical realization could be a laser with external cavity, for which the information is fed via electrical injection. A task-independent quantification of the computational capability of the res...

Dynamic signatures of mode competition in optically injected high-β lasers

Lingnau, Benjamin ; Schicke, David ; Eichelmann, Marcel ; Lüdge, Kathy (2020-07-28)

In this paper we theoretically investigate the statistical light-emission properties of an optically injected bimodal quantum-dot micropillar laser with high spontaneous emission rates. The nanostructured device is described in terms of a stochastic, semiclassically derived rate equation model. We focus on the stochastic switching dynamics between the two fundamental modes and correlate the res...
