Cascaded-Mode Resonators

Presenter: Vincent Ginis, Harvard University, United States

Presentation Details

We introduce cascaded-mode resonators. These are optical resonators where different transverse modes are coupled via a specific cascade to form a longitudinal supermode with remarkable propagation properties and a modified resonance spectrum.Authors: Vincent Ginis, Harvard University / Ileana-Cristina Benea-Chelmus, Harvard University / Jinsheng Lu, Harvard University / Marco Piccardo, Harvard University / Federico Capasso, Harvard University
