Neural networks urge for parallelism across the entire processor and for a co-location of memory and arithmetic, i.e. beyond von Neumann architectures. This feature challenges the hegemony of silicon electronics and offers promises for photonic enabled neural network processors. We realized a fully parallel and fully implemented photonic neural network using spatially distributed modes of an efficient and fast semiconductor laser. In addition, we leverage 3D photonic integration based on 3D printing, which promises photonic integrated tensor processing units with superior integration density and scaling.

Quantum communications are enabled by the availability of solid state components involving single photon emission and detection. Individual defects in semiconductors are natural candidates for the generation of single photons. Erbium in silicon emits at 1540 nm up to room temperature and therefore it would be suitable for both integrated circuits and eye-safe free space emission. I review the physics and the technology of erbium in silicon photonics as candidate for quantum communications, from recent results to possible methods to employ it in quantum protocols.

Holographic Tomography (HT) is a label-free technique for the quantitative imaging of biological specimens at the microscopic scale. Different strategies have been explored to perform HT, all of which are based on the collection of the Quantitative Phase Maps (QPMs) at different viewing angles all around the sample. The HT outcome is the three-dimensional (3D) refractive index (RI) distribution of a single cell, e.g.,red blood cells, white blood cells, cancer cells, plant cells, etc., reconstructed without the employment of exogenous contrast agents like fluorescent dyes...

Here we propose the use of the pyro-electric effect for the easy fabrication of polymer optical micro-structures and the perspective of case use as smart components Problems connected to the size and shape of the micro-structures of interest could be controlled by the printing activation from a drop reservoir, overcoming the use of nozzles. This novel approach opens the route for a practical application of direct printing on any device for multiscale inspection and measurement techniques.
