ABSTRACT We have observed that a light beam that passed through an optically active crystal of Bi(12)SiO(20) and that was then ref lected exactly back through it did not recover its initial polarization orientation. The nonreciprocal component of the rotation was of the order of 2 x 10(-3) of the reciprocal, single-pass rotation. This nonreciprocity is unambiguous evidence of broken reversality of the light-matter interaction process.

    ABSTRACT: The application of reciprocity principles in optics has a long history that goes back to Stokes, Lorentz, Helmholtz and others. Moreover, optical applications need to be seen in the context of applications of reciprocity in particle scattering, acoustics, seismology and the solution of inverse problems, generally. In some of these other fields vector wave propagation is, as it is in optics, of the essence. For this reason the simplified approach to light wave polarization developed by, and named for, Jones is explored initially to see how and to what extent it encompasses reciprocity. The characteristic matrix of a uniform dielectric layer, used in the analysis of interference filters and mirrors, is reciprocal except when the layer is magneto-optical. The way in which the reciprocal nature of a characteristic matrix can be recognized is discussed next. After this, work on the influence of more realistic attributes of a dielectric stack on reciprocity is reviewed. Some of the numerous technological applications of magneto-optic non-reciprocal media are identified and the potential of a new class of non-reciprocal components is briefly introduced. Finally, the extension of the classical reciprocity concept to systems containing components that have nonlinear optical response is briefly mentioned.

    ABSTRACT: We prove an instance of the Reciprocity Theorem that demonstrates that Kerr Rotation, also known as the magneto-optical Kerr effect, may only arise in materials which break microscopic time reversal symmetry. This argument applies in the linear response regime, and only fails for nonlinear effects and, in some cases, non-equilibrium effects. Recent measurements with a modified Sagnac Interferometer have found finite Kerr rotation in a variety of superconductors. Our result implies that the Sagnac Interferometer only measures time reversal symmetry breaking, and, thus, time reversal symmetry is broken in these materials.

    ABSTRACT: The theory of the molecular optical response in the first-order spatial dispersion approximation is developed. It is shown that in the absence of a DC electric and/or magnetic field the electric quadrupole and magnetic dipole interactions are inseparable on the microscopic level. The equations for first-, second- and third-order hyperpolarizabilities, which are responsible for such polarization phenomena as natural and light-induced polarization plane rotation and quadrupole second harmonic generation are obtained.
