Light-Harvesting, sensors, interferometers - all can benefit from resonant field enhancement in optical cavities. The effect, however, is normally limited to narrow linewidths and there is significant interest in increasing the resonant condition over extended frequency bands, i.e. achieving white-light cavities.

In this webinar hosted by the NonImaging Optical Design Technical Group, you will learn the basics and nuances of omni-resonance from Prof. Ayman Abouraddy (CREOL, University of Central Florida). He will introduce how his group implements omni-resonance by controlling the angular dispersion of light incident on cavities and applies it to, e.g., achieve coherent perfect absorption in solar cells. You will also learn how the concept can be generalized and specific spatiotemporal light structuring can be exploited to create omni-resonant space-time wave packets.

Subject Matter Level: Introductory - Assumes little previous knowledge of the topic

What You Will Learn:

  • What is omni-resonance, how can it be achieved and what are the intricacies?
  • How can the concept be extended to structured optical wave packets?
  • What are current and future applications of omni-resonance?

Who Should Attend:

  • Students and researchers of light harvesting/energy optics, structured light, and broad-band cavities
  • Anybody working with broad-band light/optics
