On-demand single-photon source for 1.3 μ m telecom fiber

We demonstrate an on-demand single-photon source that is compatible with standard telecom optical fiber. Through careful control of the critical strains of In As ∕ Ga As self-assembled quantum dots, we produce a microcavity sample with a low density of large dots emitting into the fiber-optic transm...

Description
Summary:We demonstrate an on-demand single-photon source that is compatible with standard telecom optical fiber. Through careful control of the critical strains of In As ∕ Ga As self-assembled quantum dots, we produce a microcavity sample with a low density of large dots emitting into the fiber-optic transmission band at 1.3 μ m . The second-order correlation function of the source reveals a strong suppression in the rate of multiphoton pulses at both 5 K and above 30 K . The source may be useful for fiber-optic-based single-photon applications, such as quantum metrology, quantum communications, and distributed quantum computing.
