Abstract
PURPOSE: To obtain a high mode conversion rate with a single mode waveguide layer by providing an intermediate layer between the waveguide layer and a substrate and making the waveguide layer optically anisotropic.
CONSTITUTION: The mode converter consists of a GGG substrate 21, an intermediate layer comprising (Sc, Ga) substituted YIG, a waveguide layer likewise comprising (Sc, Ga) substituted YIG and air 24. Here, if the refractive indexes of the substrate 21, the intermediate layer 22, the waveguide 23 and the air 24 are defined as n1, n2, n3, n4, respectively, there is the relation of n3>n2>n1>n4 among these. The mode conversion rate in the single mode film thickness of the waveguide layer 23 is increased by adding compressing stress owing to the mis-fit of the grating constant from the substrate 21 to the waveguide layer 23 and introducing optical anisotropy into the waveguide layer 23.
