The nonlinear interaction of elliptically polarized counter-propagating waves in an isotropic transparent medium is analysed. Self-induced changes in the polarization of the counter-propagating light waves, are described. Using these results, a new type of modulator giving self-induced rotation of the polarization ellipse (SIRPE) is studied. The transmission of counter-propagating waves in the SIRPE modulator is shown to exhibit saturation with increase in light intensity and to be a multiple-valued function of the light intensity.

A new mechanism for producing squeezed states in the third-harmonic field generated in isotropic media is discussed. It is shown that considerable squeezing is obtained if the third-harmonic field is generated by self-squeezed light resulting from a nonlinear propagation process. Analytical formulas describing this novel way of producing squeezed states are derived and illustrated graphically, showing strong correlations of squeezing in the fundamental and the third-harmonic beams.
