The dynamical response properties of photonic neuron based on vertical-cavity surface emitting lasers (VCSELs) subject to orthogonal polarized optical pulse injection stimuli have been numerically investigated. Based on the well-known spin flip model. we first reproduce some experimental findings of neuron-like dynamics in VCSELs. such as phasic spiking with a single abrupt pulse. https://parisnaturalfoodes.shop/product-category/vitamin-k-2/
