Talk Title: "The Power of Nonlinearities: Unlocking Opportunities for Sensing and Computing with Light"

Abstract

As the information age evolves, we are faced with new challenges in how to capture and process information. Nonlinearity, which leads to functions such as logic operations and frequency conversion, is a critical part of addressing these challenges. Many of today's information technologies simply would not be possible without nonlinear circuitry and integrated silicon-based transistors.

In his lecture, Alireza Marandi will describe how he and his research group are exploring scientific frontiers in nonlinear photonics, from ultrafast optics to laser spectroscopy and more, using state-of-the-art laser systems, micro and nano fabrication tools and techniques, unconventional materials, and numerical and theoretical techniques. He will also discuss the applications of those explorations to some of our most daunting modern-day inquiries in computing and sensing, including the creation of universal breath-analysis devices.

KNI-Wheatley Scholarship in Nanoscience

Alireza Marandi has been named the 2019 KNI-Wheatley Scholar in Nanoscience for his proposal to develop and study resonator-based quadratically nonlinear nanophotonic devices. Introducing strong quadratic nonlinearities to photonics can enable development of disruptive technologies for numerous applications. This is evident from more than 50 years of table-top nonlinear optics, through which a wide range of optical systems with extraordinary performance has been demonstrated for applications ranging from sensing to computing. Marandi's project is focused on bringing the depth and breadth of such functionalities to the nanoscale integrated photonics and enabling scalable solutions for a variety of applications.

Marandi's research group is focused on fundamental technological developments in nonlinear photonics enabling innovative, practical, and scalable solutions for these challenges. His team explores the frontiers of ultrafast optics, optical frequency combs, quantum optics, optical information processing, mid-infrared photonics, and laser spectroscopy. In their research, they use state-of-the-art laser systems, micro and nano fabrication tools and techniques, unconventional materials, and numerical and theoretical techniques. While their main goal is experimental realization of novel nonlinear photonic systems, techniques, and technologies, they also work on advancing the theoretical understanding of these systems as well as applying their solutions to real-life problems.
