ABSTRACT:
The present invention is directed to an improvement in a magneto-optical device having a light waveguide for conducting light characterized by the light waveguide being a cladded optical fiber having a core of quartz glass and a cladding of synthetic material. This improvement provides an improved method of using the magneto-optical device by suppressing distortions of polarized light by reducing birefringence in the waveguide by using a waveguide comprising an optical fiber having a quartz glass core and a cladding of synthetic material.
