Photonic technologies lack non-invasive monitoring tools to inspect the light inside optical waveguides. This is one of main barriers large scale integration, even though photonic platforms are potentially ready host thousands elements on a single chip. Here, we demonstrate observation in silicon photonics devices by exploiting photon interaction with intra-gap energy states localized at waveguide surface.

Embedding signal processing in the front-end of radiation detectors represents an approach to cope with growing complexity nuclear imaging scanners increasing field view (i.e., higher number channels). Machine learning (ML) offers a good compromise between intrinsic image reconstruction performance and computational power. While most hardware accelerators for ML are based on digital circuits and, thus, require analog-to-digital conversion all individual signals from photodetectors, analog...
