Abstract
We demonstrate a spectrally broadband and efficient technique for collecting photoluminescence from a single InAs quantum dot directly into a standard single mode optical fiber. In this approach, an optical fiber taper waveguide is placed in contact with a suspended GaAs nanophotonic waveguide with embedded quantum dots, forming an efficient and broadband directional coupler with standard optical fiber input and output. Efficient photoluminescence collection over tens of nanometers is demonstrated, and a maximum collection efficiency of 6.05 % (corresponding single photon rate of 3.0 MHz) into a single mode optical fiber was estimated for a single quantum dot transition.Citation
