The third-order process of spontaneous four-wave mixing (SFWM) has seen increasing use due to the CMOS-incompatibility and difficulty of integrating second-order material platforms, as well as due to the presence of third-order nonlinearities in common platforms. In integrated optics, SFWM's low efficiency is often compensated using on-chip nonlinear microcavities [1], however, excitation schemes...
