  • We have measured the amount of nonreciprocal circular birefringence of 50 to 800 A YBa{sub 2}Cu{sub 3}O{sub 7} films in transmission with a 15-{mu}m beam diameter. A novel instrument with a sensitivity of 2 {mu}rad for nonreciprocal phase shifts was developed by modifying a fiber-optic gyroscope. It is insensitive to reciprocal phase shifts. We observed no nonreciprocal phase shifts in any samples.
  • A nonlinear (dependent on the output radiation power) non-reciprocal effect associated with the difference between the ellipticity of the opposite waves was investigated in a ring laser (at the wavelength of 1.15 in which the active medium was subjected to a longitudinal magnetic field. The results of the experiments were used to estimate the parameters of resonant trapping of radiation in the active medium.
  • Equations are derived for the description of steady-state multimode operation of a ring laser in an arbitrarily oriented magnetic field in the case when the resonator anisotropy is much stronger than the anisotropy of the active medium induced by the magnetic field. The transverse component of the magnetic field gives rise to nonreciprocal effects of two types: one of them is a polarization nonreciprocal effect which is due to a difference between the coefficients describing the nonlinear interaction of waves in an active medium and which depends on the ellipticity Epsilon of the radiation as Epsilon(1-Epsilon/sup 2/)/(1+Epsilon/sup 2/)/sup 2/; themore » other is a dispersion nonreciprocal effect which is due to an asymmetry of the frequencies of the opposite waves in the ring laser relative to the gain curve and which, in contrast to the former effect, is observed in the case of linear and circular polarizations of the radiation. Computer calculations are reported of the dependences of these effects on the intensity and direction of the magnetic field in the case of active medium and resonator parameters of the kind usually encountered in experiments.« less
  • We report the fabrication of a 20-{mu}m-thick photorefractive Fe:LiNbO{sub 3} planar waveguide buried in MgO:LiNbO{sub 3} by direct bonding of precision polished surfaces. Nonreciprocal transmission measurements were performed in a 3-mm-long device with a continuous wave 532 nm frequency-doubled YAG laser source. A Fresnel-reflection-based counterpropagating beam arrangement was used to measure a relative change in optical density of approximately 2 within the waveguide, with a photorefractive response time of 4.9 ms. {copyright} 2001 American Institute of Physics.
