Neuromorphic photonic approaches, focusing on implementation of brain-inspired hardware, have recently gained significant interest. Among those, vertical cavity surface emitting lasers (VCSELs) offer multiple desirable properties while exhibiting fast spiking responses. We utilize their functionality to experimentally realize temporal spike-based encoding of pixel intensity values from digital images. The image data is represented as continuous, rate-coded optical spike trains. Reconstruction from the spike rates shows very good agreement with the source images.
