Abstract
We report on the highly-efficient generation of narrow-band pair-photons in one single spatiotemporal mode using parametric down-conversion in a crystalline whispering gallery mode resonator. We developed the requirements on phase-matching conditions in spheroidal geometries to achieve single-mode operation. Its precise understanding facilitates the realization of the highest reported single-mode pair-detection rate of 0.97 Million pairs/s per mW pump power per 20 MHz bandwidth without the need of additional filter cavitiesCitation
