Now Available. CS-TC03: Single-Mode, Narrow Band Photon Source Using SPDC for Hybrid Quantum Systems
Researchers at the University of Vienna have designed a photon source using Spontaneous Parametric Down-Conversion (SPDC) with a doubly resonant Optical Parametric Oscillator (OPO) utilizing an additional birefringent crystal to tune clusters independent of SPDC phase-matching. Achieving the doubly resonant condition in the OPO that enables a single mode is challenging. This photon source has a bandwidth of 10.9 MHz to match the linewidths of atomic transitions. The source also produces single-mode photon pairs at a rate of 47.5 Hz without mode filters reducing loss in the system, which enables research and applications in the quantum realm using hybrid light-matter interactions.
The complete case study is available as CS-TC03.
