The author aims at merging polarization optics and non-linear optics for non-linear Fabry-Perot cavities. The in-depth study shows, both from a stationary and a dynamical approach, that polarization modulation leads among others to a novel switching mechanism. Furthermore, in well defined circumstances, using e.g., anisotropic cavity materials, polarization optical bistability can occur. Aspects of the dynamics of these processes are highlighted and applications are suggested.

Documenting (1977) and Bloembergen (1979) have suggested that resonances between unpopulated levels should be observed in non-linear optics. Using the theory of the dressed atom, the author shows that these resonances correspond to the pumping of a coherence of the dressed atom because of the collisions. He shows that these resonances are closely related to the collisional redistribution of radiation. Finally, he shows that these resonances can generally be observed only in the frequency range where the impact approximation can be applied.
