Artificial Intelligence Plenary

Session Chair: Daniel Brunner, FEMTO-ST (France)
5:00 PM - 5:05 PM:
Welcome and Opening Remarks
5:05 PM - 5:45 PM:
Optical nonlinearity in integrated circuits using spatiospectral reconfiguration concepts
Photonic computing has become big business - even before we address the question of whether all components required to make a computer even exists. And even before we look at neuromorphic computing as THE viable alternative to solve current compute challenges. In this talk, I will start a little bit about the history of computing and the opportunity that this confluence of need, maturity of photonic components and a trained workforce mean for this technology. Particularly, I shall focus on the advances made by several researchers in my research group at Oxford over the years from on-chip photonic memory devices to analog processing using such memories (in-memory photonic computing as well as neurosynaptic computing), issues with scaling these up and how we now can achieve optical control over other optical signals through a phonon-assisted process. This would potentially enable integrated nonlinearity to be configured in integrated circuit in a fast and seamless manner. The use of spatiospectral concepts with integrated nanoantennas enables us to use thermal interaction to mediate photon-photon interactions which I will present in this talk.
Harish Bhaskaran is Professor of Applied nano materials at Oxford (currently on leave and working at a major semiconductor firm in Silicon Valley). He is an inventor of the photonic tensor core and other optoelectronic concepts. After a PhD in Mechanical Engineering at the University of Maryland College Park, he worked at IBM Research - Zurich on phase change materials and atomic force microscopy; following a short postdoc at Yale, he became a Leturer (Assistant Professor) at the University of Exeter and then Associate Professor at the University of Oxford, where he then became Professor of Applied Nanomaterials. He is an elected fellow of Optica, the Institution of Mechanical Engineers as well as a Fellow of the Royal Academy of Engineering.
SETUP: Theater style seating.
