“…However, as we mentioned in the Introduction, the situation is very different in the nonlinear optical regime. The dependence of material parameters on the intensity of light can lead to polarization bistability, multistability [12,13,17,18] or even to polarization chaos [19]. These effects manifest themselves in such a way that the output wave polarization state becomes a multivalued function, containing both stable and unstable branches.…”

Optical properties of a one-dimensional photonic structure consisting of Kerr-type nonlinear and magnetic layers under the action of an external static magnetic field in the Faraday geometry are investigated. The structure is a periodic arrangement of alternating nonlinear and magnetic layers (a one-dimensional photonic crystal) with one of the layers doubled to create a defect where periodicity is violated. Strong enhancement of nonreciprocity is observed at the frequencies of the defect modes, where linearly polarized light incident from one side of the structure undergoes 90 • polarization rotation upon reflection, while light reflected from the other side has its polarization unchanged. Using the nonlinear transfer matrix calculations in the frequency domain, it is demonstrated that defect resonances in the nonlinear reflection spectra undergo bending, resulting in polarization bistability of reflected light. This bistability is shown to result in abrupt switching between linear polarization of the output reflected light when the input intensity is varied. This switching is confirmed in finite-difference time-domain simulations, and its hysteresis character is established.

“…The main distinctive feature of an MPC in contrast to the nonmagnetic one is the ap- the longitudinal Zeeman-like doublets 16 . These doublets originate from lifting of the degeneracy between resonant conditions for the LCP and RCP waves in the underlying MPC by the external magnetic field.…”

“…In this paper, we consider an MPC where a nonlinear defect which is placed either symmetrically or asymmetrically inside the periodic structure. An important feature of the studied system is the fact that the asymmetric bistable transmission is accompanied by the polarization conversion [15][16][17] . The main objective of our study is focused on achieving the bistabilityinduced abrupt switching between two distinct polarization states.…”

Polarization switching and nonreciprocity in symmetric and asymmetric magnetophotonic multilayers with nonlinear defect

A one-dimensional magnetophotonic crystal with a nonlinear defect placed either symmetrically or asymmetrically inside the structure is considered. Simultaneous effects of time-reversal nonreciprocity and nonlinear spatial asymmetry in the structure are studied. Bistable response is demonstrated in a such system, accompanied by abrupt polarization switching between two circular or elliptical polarizations for transmitted and reflected waves. The effect is explained in terms of field localization at defect-mode spectral resonances and can be used in the design of thin-film optical isolators and polarization transformation devices.

“…The photospin-orbit splitting of the eigenmodes in photonic crystals with optical activity present is analogous to an effective Zeeman-like splitting [9] by a magnetic field whose magnitude and direction follow those of the wave vector. As can be inferred from Eq.…”

We show that the inclusion of nonlocality in the constitutive relations in photonic structures has important repercussions in their eigenmode configuration and distribution. In the case of optical activity, the primary manifestation of nonlocality, these features are traced to a photospin-orbit interaction analogous to the electron spin-orbit interaction in asymmetric semiconducting compounds; its impact can be assimilated to that of a magnetic field whose magnitude and direction follow that of the photon quasimomentum, with implications in photospin transport and photospintronics.
