Loss-tolerant hybrid metasurface mirror for reducing coating Brownian noise in precision optical cavities
Swadha Pandey, Evan D. Hall, Peter Fritschel +1
We propose a hybrid mirror design that places an embedded metasurface beneath a Bragg reflector, combining the low coating Brownian noise of metasurface mirrors with the low optica…

Coating-free monolithic fused silica resonator via total internal reflection for precision laser stabilization
Swadha Pandey, Rodica Martin, Peter Fritschel +2
Brownian noise in the thin-film mirror coatings of optical reference cavities is a fundamental limitation in precision metrology, including gravitational-wave detectors and optical…
