Webb7 dec. 2024 · Thermorefractive fluctuations can severely limit Q/V, so they have to be handled, or better, countered. In principle, there are paths to reducing the TR noise. These include working at cryogenic temperatures [ 9 ] or counterbalancing the TR noise of the cavity by cladding it with a material with the opposite thermorefractive response [ 10 ].
