Summary
Coupled ring induced transparency (CRIT) resonances offer significantly higher quality factors. Engineered CRIT resonances in tapered SCISSOR devices enable fast, efficient reconfigurable optical switches and routers for multiple channels.
Area of Science:
- Photonics

- Materials Science
Background:
- Resonator sequences can exhibit coupled ring induced transparency (CRIT) resonances.
- CRIT resonances possess quality factors significantly higher than individual resonators.
- Tapered SCISSOR (Side Coupled Integrated Space Sequence of Resonator) devices offer potential for optical switching applications.
Purpose of the Study:
- To engineer CRIT resonances in tapered SCISSOR devices.
- To demonstrate fast and efficient reconfigurable optical switches and routers.
