Abstract

PURPOSE:To obtain waveguide type Farady rotating element which works at a single mode, can be connected to another waveguide type element directly, and has a small impressed magnetic field, by forming double epitaxial layers composed of a waveguide layer and an intermediate layer on a gadolinium-gallium-garnet substrate. CONSTITUTION:A double epitaxial layer of a waveguide layer 1 composed of substitutional type yttrium, iron, and garnet is formed on a gadolinium-gallium-garnet substrate 3 with an intermediate layer 2 composed of substitutional type yttrium, iron, and garnet in between. When the refractive index of the layer 1 is made larger than that of the layer 2, and, at the same time, the layer 1 is formed so as to represent an optical anisotropy, the incident light at the time of magnetic field impression becomes a radiating light whose plane of polarization is rotated in accordance with the propagation distance of the layer 1. Moreover, when the thickness D1 of the layer 1 is set to a prescribed one, the conversion ratio between the TEO mode and the TMO mode becomes 100%, and this element works at single mode. Therefore, this element can directly be connected to another waveguide element, and becomes a waveguide type Farady rotating element having a small impressed magnetic field.
