1Torsional optomechanical cooling of a nanofiber显示文摘We demonstrate the optomechanical cooling of a tapered optical nanofiber by coupling the polarization of light to the mechanical angular momentum of the system. The coupling is enabled by birefringence in the fiber and does not make use of an optical resonator. We find evidence for cooling in the distribution of thermally driven amplitude fluctuations and the noise spectrum of the torsional modes. Our proof-of-principle demonstration shows cavity-less cooling of the torsional degree of freedom of a macroscopically extended nanofiber.Dianoiang Su Pablo Solano Jeffrey D.Wack Luis A.Orozco Yanting Zhao 2022Photonics Research2022,10,2:1
2Optomechanical feedback cooling of a 5 mm long torsional mode显示文摘We report three orders of magnitude optical cooling of the fundamental torsional mode of a 5 mm long,550 nm diameter optical nanofiber.The rotation of the nanofiber couples to the polarization of guided laser fields.We use a weak laser probe to monitor the rotation and use feedback to modulate the polarization of an auxiliary drive laser providing torque.Our results present a tool for the optomechanical control of large-scale torsional resonators,with metrological applications and potential implications for studying macroscopic objects in quantum states.DIANQIANG SU YUAN JIANG PABLO SOLANO LUIS A.OROZCO JOHN LAWALL YANTING ZHAO 2023Photonics Research2023,11,12:0
