Abstract: In the context of quantum integrated photonics, this work investigates the quantum properties of multimode light generated by silicon and silicon nitride microresonators pumped in pulsed regime. The developed theoretical model provides a comprehensive description of the generated quantum states. Remarkably, it shows that a full measurement of states carrying optimal squeezing levels is not accessible to standard homodyne detection, thus leaving hidden part of generated quantum features. By unveiling and discussing this behavior and possible strategies to amend it, this work proves itself essential to future quantum applications exploiting microresonators as sources of multimode states.
