 Light-matter interactions based on optical nanofiber
The nanofiber is stretched by flame brushing. The diameter of the nanofiber is 500 nm over a length of 5 mm fabricated from a single mode fiber (Fibercore, SM800-5.6-125). Waveguided light is tightly confined near the nanofiber surface and interacts with the trapped atoms.
 Optomechanical cooling of nanofiber torsional mode
The torsional mode motion of nanofiber is induced by the thermal noise. Linearly polarized light can exert a torque on a birefringent object when passing through it. We demonstrate the optomechanical cooling of a tapered optical nanofiber by coupling the polarization of light to the mechanical angular momentum of the system.
