“…Entangled and single photon sources are a key ingredient in a wide range of applications of quantum information, including quantum computation, 1,2 communication, 3,4 cryptography, [5][6][7] and quantum metrology. 8 They are based on nonlinear optical effects, among which one can mention parametric down conversion 9,10 and quantum dots exploiting the Purcell effect. 11,12 Modern quantum technologies are trying to achieve scalability by using integrated photonic quantum circuits on chip, for example, for boson sampling.…”

We study the feasibility of generating photon pairs in a resonant Vertical-Cavity Surface-Emitting Laser (VCSEL) as a result of a third-order non-linear, four wave mixing interaction. We focus on degenerate four wave mixing in the spontaneous regime where two pump photons are annihilated to create a pair of signal and idler photons. Using the methods of quantum optics, we calculate the two-photon production rate, the spectrum of the generated photons, and the signal-idler cross-correlations. We highlight how the dispersion of the medium in the VCSEL cavity (a regular GaAs configuration) significantly diminishes the two-photon production rate. Based on our results, we enumerate the characteristics of a VCSEL that would be suitable for photon pair generation.
