Nonlinear power dependence of the spectral properties of an optical parametric oscillator below threshold in the quantum regime
Golnoush Shafiee, Dmitry V. Strekalov, Alexander Otterpohl +6
Photon pairs and heralded single photons, obtained from cavity-assisted parametric down-conversion (PDC), play an important role in quantum communications and technology. This moti…
