Abstract: The PELM project aims at developing new photonic devices for “machine learning”. Within a single neuromorphic computing architecture, different platforms are used and optimized for certain tasks based on specific characteristics. Starting from a common algorithm, through a neural network, highly innovative principle systems are created such as: sequence of optical resonators with micro-rings integrated in silicon, metasurfaces of nanowires for the synthesis of arbitrary optical functions, liquid “whispering gallery” resonators, biological resonator spheres. The unique combination of the different devices with the neural network and the light-matter interaction effects (scattering, polarization variation, absorption, resonances) allow for the creation of highly sensitive “learning machine” prototypes, opening new frontiers for AI applications in diagnostics bio-medical, autonomous driving and telecommunications
