Limitations of Microresonators as Heralded Single Photon Sources

Abstract

We demonstrate a fundamental limitation of the use of microresonators as heralded single photon sources. Such sources suffer from a tradeoff between heralding efficiency and heralding rate, which depend sensitively on the resonator-channel coupling.

No free lunch: the trade-off between heralding rate and efficiency in microresonator-based heralded single photon sources

Z. Vernon, M. Liscidini, J. E. Sipe

Generation of heralded single photons has recently been demonstrated using spontaneous four-wave mixing in integrated microresonators. While the results of coincidence measurements on the generated photon pairs from these systems show promise for their utility in heralding applications, such measurements do not reveal all of the effects of photon losses within the resonator. These effects, which include a significant degradation of the heralding efficiency, depend strongly on the relative strengths of the coupling of the ring modes to loss modes and channel modes. We show that the common choice of critical coupling neither optimizes the rate of successfully heralded photons nor coincidences and derives the coupling conditions needed to do so. Optimizing these rates has a considerable negative effect on the heralding efficiency.

Limits of heralded single-photon sources based on parametric photon-pair generation

We derive calculations on the statistics of a heralded single-photon source based on parametric photon-pair generation. These calculations highlight fundamental and practical limits for these sources and show which physical parameters can be optimized to improve the quality of a real source.

We study the role of spectral and spatial correlations between SPDC photons in the heralding efficiency and purity of heralded single photon sources. Our results depend on the photon chosen to herald due to birefringence.
