DESCRIPTION:Abstract: The undepleted pump approximation is typically valid 
 for squeezed light generation in microring resonators with a third-order n
 onlinearity\, such as silicon nitride (SiN)\, because the process is not e
 fficient enough to significantly deplete the pump. However\, recent work o
 n second-order nonlinear processes in indium gallium phosphide (InGaP) mic
 rorings has demonstrated high conversion efficiency of the pump\, suggesti
 ng that the undepleted pump approximation may no longer hold in such cases
 . In this talk\, I will present recent theoretical and numerical results o
 n spontaneous parametric downconversion (SPDC) in InGaP microrings\, where
  we find evidence of non-Gaussianity arising from the efficient conversion
  of pump photons into signal and idler photons. This work opens a path tow
 ard the deterministic generation of non-Gaussian states on-chip.\n\nCo-spo
