Stochastic birhythmicity outside the coexistence region in the Hindmarsh-Rose model
Ignacio Ortega-Piwonka, Javier Used, Jesus M. Seoane +1
In this work, we demonstrate that the Hindmarsh-Rose model subjected to additive white noise exhibits birhythmicity. Specifically, the system fluctuates between two distinct bursti…
Artificial optoelectronic spiking neuron based on a resonant tunnelling diode coupled to a vertical cavity surface emitting laser
Matěj Hejda, Ekaterina Malysheva, Dafydd Owen-Newns +9
Excitable optoelectronic devices represent one of the key building blocks for implementation of artificial spiking neurons in neuromorphic (brain-inspired) photonic systems. This w…
Resonant tunnelling diode nano-optoelectronic spiking nodes for neuromorphic information processing
Matěj Hejda, Juan Arturo Alanis, Ignacio Ortega-Piwonka +5
In this work, we introduce an optoelectronic spiking artificial neuron capable of operating at ultrafast rates ( 100 ps/optical spike) and with low energy consumption (…
Bursting and excitability in neuromorphic resonant tunneling diodes
Ignacio Ortega, Oreste Piro, Bruno Romeira +1
We study in this paper the dynamics of quantum nanoelectronic resonant tunneling diodes (RTDs) as excitable neuromorphic spike generators. We disclose the mechanisms by which the R…
