Planar optical waveguide and method of manufacturing same

摘要

Planar optical waveguide having a crystal body consisting of a nonmagnetic substrate having a first magnetooptical layer epitaxially provided on the substrate and a second magnetooptical layer epitaxially provided on the first mangetooptical layer. The two magnetooptical layers consist of a material based on iron garnet. The second magnetooptical layer has a refractice index n2 which is approximately 1x10-3 to 1x10-2 higher than the refractive index n1 of the first magnetooptical layer. A layer of a material based on iron garnet and absorbing radiation in the wavelength range of 1.0
