Quantum Photonics on a Tapered Optical Fiber

A tapered optical fiber with subwavelength diameter waist, an optical nanofiber, provides a unique and all-fiber platform for manipulating atoms and photons. This paper presents some recent results towards quantum photonics on a nanofiber platform. In one direction, we demonstrate a quantum interface between trapped single atoms and fiber-guided photons using a nanofiber cavity. In the other direction, we demonstrate a polarized fiber-in-line quantum light source using a hybrid system of a single gold nanorod and single quantum dot deposited on a nanofiber.
