Abstract: This invention discloses an optical circulator compatible with optical glass fiber transmission lines in optical communications in the wave length range of 1.0.about.1.7 microns. An optical circulator embodiment of the invention utilizes a magneto-optic circulator cylinder with the entry and reflective ends, at least three coupling glass-fiber transmission lines being connected to the entry end. The biasing magnetic field is applied in parallel with the common axis. This circulator embodiment of the invention possesses advantages in consisting of minimal constituents, and in being easy to make and simple to adjust.

Abstract: An optical wave circulator of the invention utilizes the coupled hybrid mode of split magneto-optical circular-cylindrical-transmission-line (MOTL) waves, with the biasing magnetic field applied parallel to the common axis. Coupling between waves of optical glass fiber transmission lines (GFTLs) and those of the MOTL can be made through openings of the MOTL junction. Forward-to-forward traveling wave coupling, forward-to-backward traveling wave coupling and others perform important roles in achieving circulations. Use of more than a single operating point for circulator performance can be made to obtain broadband and diplexer operations in the optical waves.

Abstract: An optical circulator in which a cubic prism for a signal coupler, a lens-like magneto-optic structure, and a reflecting structure are utilized as important constituents acts a role of circulation in optical region. Basic features of the optical circulator are such that a signal light cumulatively effects the Faraday rotation on repeated passages through the magneto-optic structure and therefore a shortened magneto-optic structure will provide sufficient roles in performing a circulator action, and furthermore, such multiple passage of the signal light will introduce useful resonant modes in the magneto-optic structure in order to produce operating modes which can achieve various multiple circulation frequency operations in the optical region. And also the optical circulator has low loss characteristics and broad availability especially in the field of optical communication.

Abstract: A three port optical wave circulator, comprising a cylindrical structure made of magneto-optic material which is optically anisotropic in a biasing magnetic field, for selectably transmitting a light beam incident to a port on the cylinder surface in a direction plus or minus 120.degree. from the incident direction. In the presence of a selected biasing magnetic field, a light beam incident to any port of the circulator is uniformly transmitted in the selected direction to a second port.

Circulator performances are categorized into broadband operation, frequency dividing operation, and others, from the viewpoint of multiple circulation frequency operation. These operations have a common basis on the finding of multiple circulation frequency operation which has been achieved with a ferrite-dielectric composite circulator. Three types of ferrite composites used are a ferrite-conductor composite, a ferrite-dielectric-conductor composite, and a ferrite-ferrite composite.
