Abstract: The invention relates to a planar optical isolator having a magneto optical gyrotropic layer and an anisotropic birefringent layer which are proportioned so that the non-reciprocal rotation of polarisation of the light (Faraday rotation) resulting from the action of a magnetic field in the forward direction of the isolator is at least substantially negatively equal to the reciprocal rotation of polarisation as a result of the birefringence, so that a TE-mode in the forward direction is guided with low damping, measures being taken for the intensive attenuation of at least one TM-mode. An isolator having a high isolating effect in which magneto optical gyrotropic layers and anisotropic birefringent layers can be connected epitaxially is obtained in that the waveguiding core layer comprises two rare earth-iron garnet (YIG) layers which are differently doped to obtain different specific birefringence.

Abstract: The invention relates to a non-reciprocal optical element, particularly for use an an isolator or circulator, which is connected to at least two monomode optical waveguides and which has a magneto-optical waveguide structure which is subjected to a transversal magnetic field directed perpendicularly to the direction of propagation of the optical wave. This arrangement is simplified by combining the functions of the coupler and the phase shifter, which is achieved by means of the following features:the magneto-optical waveguide structure (1,11) is formed as a multimode waveguide which can propagate at least one fundamental mode (5) and the first-order mode (6),the optical waveguides (A,B,C,D,9,10) are off-centered with respect to the waveguide structure (1,11),the dimensions and/or the cross-sectional distribution of the refractive index of the optical waveguide structure (1,11) are chosen to be such that the two modes (5,6) have a reciprocal phase difference of (.pi.2)+pb 2n.pi.

Abstract: The invention relates to an arrangement of inspecting light waveguide end faces by observing the interference pattern formed by means of measuring light in the airgap between a plane transparent plate and the end face of a light waveguide abutting on said plate.
