• Abstract: We experimentally demonstrate a spectral compression scheme for heralded single photons with narrow spectral bandwidth around 795 nm, generated through four-wave mixing in a cloud of cold Rb-87 atoms. The scheme is based on an asymmetric cavity as a dispersion medium and a simple binary phase modulator, and can be, in principle, without any optical losses. We observe a compression from 20.6 MHz to less than 8 MHz, almost matching the corresponding atomic transition.

  Integrated continuously tunable laser in a heterogeneous gallium arsenide-on-silicon nitride (GaAs-on-SiN) platform. Laser emits in the far-red radiation spectrum near 780 nm, with 20 nm tuning range, 6 kHz intrinsic linewidth, and a >40 dB side-mode suppression ratio. The proposed integrated laser holds promise for a broader spectrum of both classical and quantum applications in the visible range.

  We show that dominant recombination through neutral exciton states can be achieved by careful control of the doping profile near an epitGa InAs/As quantum dot placed in a columnar microcavity with distributed Bragg. Experiments carried out in the fabricated reflectors demonstrate the degree of indistinguishability of 91% of emitted single photons within 242 ns at an efficiency of 10% inside a single-mode optical reflectors.
