Statistical Computing in Photonic Integrated Circuits
2018 Photonics in Switching and Computing (PSC), 2018Artificial Neural Networks (ANN) have dramatically improved performance for many machine learning tasks. We demonstrate new architectures based on Photonic Integrated Circuits for carrying out ANN and other statistical processing tasks. I will discuss how it can enable orders of magnitude enhancement in computational speed, latency and power efficiency

Photonic Crystals—A Step towards Integrated Circuits for Photonics
ChemPhysChem, 2004AbstractThe field of photonic crystals has, over the past few years, received dramatically increased attention. Photonic crystals are artificially engineered structures that exhibit a periodic variation in one, two, or three dimensions of the dielectric constant, with a period of the order of the pertinent light wavelength.

The power of circuit simulations for designing photonic integrated circuits
Concurrency and Computation: Practice and Experience, 2014SUMMARYThe emerging of circuit‐level simulators for photonic integrated circuits (PICs) is driven by recent developments in technologies for integration of large‐scale monolithic PICs in both, silicon and InP technologies. For that reason, powerful circuit‐level simulators should be capable to model on the same circuit different types of sub‐components

Photonic Integrated Circuits for microwave photonics
2010 IEEE International Topical Meeting on Microwave Photonics, 2010InP-based Photonic Integrated Circuits (PICs) have found applications in the telecommunication and sensing arena because they have offered improvements in cost and function as well as size, weight and power. For microwave photonics applications, it has been found that some analog functions such as optical-phase locked loops (OPLLs) can be greatly ...

Photonic Integrated Circuits Using Heterogeneous Integration on Silicon
Proceedings of the IEEE, 2018Heterogeneous silicon photonics using wafer bonding is reaching maturity with commercial products for the data center market being shipped in volume. Here we give an overview of recent research in the area showing record device performance by using the best of both worlds: III–V for light generation and Si for guiding the light.
