Images formed by light exhibiting suppressed photon fluctuations represent an interesting object of investigation from the point of view of increasing the limiting information capacity of devices. Light with such properties can be prepared in a cavity filled by a nonlinear medium, in which light experiences self-phase modulation. Multimode light beams are studied and spatial frequency spectra of suppressed photon fluctuations are obtained. Efficient operating regimes of the system are found.

We analyze the formation of polarization-squeezed light in a medium with electronic Kerr nonlinearity. Quantum Stokes parameters are considered and the spectra of their quantum fluctuations are investigated. It is established that the frequency at which the suppression of quantum fluctuations is the greatest can be controlled by adjusting the linear phase difference between pulses. We shown that by varying the intensity or the nonlinear phase shift per photon for one pulse, one can effectively control the suppression of quantum fluctuations of the quantum Stokes parameters.
