Spontaneous four-wave mixing in microring resonators

Opt Lett. 2010 Sep 15;35(18):3006-8. doi: 10.1364/OL.35.003006.


We consider spontaneous four-wave mixing in a microring resonator, presenting photon-pair generation rates and biphoton wave functions. We show how generation rates can be simply predicted from the performance of the device in the classical regime and that a wide variety of biphoton wave functions can be achieved by varying the pump pulse duration.
