Numerical implementation of wavelength-dependent photonic spike timing dependent plasticity based on VCSOAï¼»

Respuesta :

A photonic system exemplifying the biological neural process of spike timing dependent plasticity (STDP) is experimentally demonstrated using nonlinear polarization rotation. STDP represents the neuronal responses for learning based on input/output timing, order, and sequence.

What is Photonic implementation of spike timing dependent plasticity with weight-dependent learning window based on VCSOA ?

according to the present synapse weight, we implement the optical spike timing dependent plasticity (STDP) with weight-dependent learning window in a VCSOA with double optical spike injections,

  • and numerically investigate the corresponding weight-dependent STDP characteristics.

  • The simulation results show that, the bias current of VCSOA has significant effect on the optical STDP curve.

  • After introducing an adaptive variation of the bias current according to the present synapse weight, the optical weight-dependent STDP based on VCSOA can be realized
