Paper Abstract

Bright fiber-coupled single photon sources are essential components for practical quantum network. In this work, we present a bright single photon source based on an InAs/InP quantum dot emitting at telecom wavelengths. We designed a nanobeam with a photonic crystal mirror at the other end and a tapered coupler at the other end enabling both directional emission and gaussian-like far-field profile. We detected fiber-coupled single photon count rate of 1.1 MHz with 40 MHz pumping rate. Considering losses from optics and spectral filters, we achieved collection efficiency into first lens of 68% and a total fiber collection efficiency of 8.2%.
