We analyze elasto-optic noise - the effect of Brownian dimensional fluctuation on frequency via the strain-dependence of the refractive index - a noise term that has so far not been considered for whispering-gallery resonators. We find that dimensional fluctuation sets a lower limit of 1E-16 to the Allan deviation for a 10-millimeter-radius sphere at 5 K, predominantly via induced fluctuation of the refractive index.", "revisions": [ { "version": "v2", "updated": "2012-03-28T06:07:19.000Z" } ], "analyses": { "subjects": [ "42.60.Da", "05.40.Jc", "06.30.Ft" ], "keywords": [ "thermal noise", "crystalline caf2 whispering gallery resonators", "analyze elasto-optic noise", "refractive index", "dimensional fluctuation sets" ], "tags": [ "journal article" ], "publication": { "doi": "10.1103/PhysRevA.85.053814", "journal": "Physical Review A", "year": 2012, "month": "May", "volume": 85, "number": 5, "pages": "053814" }, "note": { "typesetting": "TeX", "pages": 7, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2012PhRvA..85e3814C" } } }
