N2 - A quantized optical cavity mode controlled by dissipation, squeezed-light source and feedback loop is studied. The feedback is activated by detections of photons leaving the cavity and rapidly shifts the phase of the cavity field by π. The steady-state of the mode and first-order field correlation functions are obtained in closed analytical form and investigated. It appears that the feedback radically modifies the mode's spectrum. It gains asymmetry and its double-peaked structure becomes much more pronounced than in no-feedback case.
