Non-classical Photon Emission from a Single InAs/InP Quantum Dot in the 1.3-µm Optical-Fiber Band

Abstract

We report the first observation of single-photon emission from a single InAs/InP quantum dot at a telecommunication wavelength. The single quantum dot was developed through a `double-cap' growth method using metalorganic chemical vapor deposition, and its emission covers a wide spectral range of the optical telecommunication band. Using a pulsed excitation source and gated single-photon detection modules, we observed a photon antibunching behavior through a single-mode optical fiber for an isolated exciton emission line at 1277.1 nm in the O-band (1.3 µm).
