A Dark Optical Mode Raised the Gain
An electrically tunable bound state suppressed radiative loss inside a silicon-nitride microresonator.
Published Updated Story ID: mp-2026-08-10-018
Summary
An electrically tunable bound state suppressed radiative loss inside a silicon-nitride microresonator.
The team reports quality factors above one million, a 12-decibel gain increase and a 1.6-decibel lower oscillation threshold when one participating mode was tuned dark. The work combines theory and experiment in an integrated device.
Why it matters
