Visible-to-Telecom Quantum Frequency Conversion of Light from a Single Quantum Emitter
Visible-to-Telecom Quantum Frequency Conversion of Light from a Single Quantum Emitter
We demonstrate efficient (>30%) quantum frequency conversion of visible single photons (711 nm) emitted by a quantum dot to a telecom wavelength (1313 nm). Analysis of the first- and second-order coherence before and after wavelength conversion clearly proves that pivotal properties, such as the coherence time and photon antibunching, are …
