Don’t worry, be happy: A look at undesirable nonlinear effects in integrated photon pair sources based on spontaneous four-wave mixing
L. G. Helt, Michael J. Steel, John E. Sipe · 2013
We theoretically demonstrate that if pump powers are kept low enough to suppress multi-pair events in integrated photon pair generation via spontaneous four-wave mixing, many other nonlinear effects are often also constrained to negligible levels.
