​Materials for Nonreciprocal Photonics

For photonic systems, breaking reciprocity using nonreciprocal materials is a fundamental challenge and opportunity, which is both of scientific interest and of technical importance. It allows for the development of key photonic components, such as optical isolators and circulators-on-a-chip and also provides revolutionary ways to transport and process data in photonic systems. In the June, 2018 issue of MRS Bulletin, several representative research directions toward realizing integrated nonreciprocal photonic materials and devices are summarized.

The talks in this webinar expanded upon the MRS Bulletin issue, and attendees were able to interact—in real time—with the webinar presenters.
