Optical TE–TM mode conversion in double epitaxial garnet waveguide

Not Accessible

Your library or personal account may give you access

Abstract

TE–TM mode conversion was examined in two-layer epitaxial garnet films, with (Sc, Ga) substituted YIG films on a GGG substrate. Mode conversion efficiency of 96% was observed in a single-mode waveguide over a 4.0-mm propagation distance at 1.15-μm wavelength. Mode conversion was increased by 2.0 × 10−4 optical anisotropy arising from the photoelastic effect of a 0.03% lattice mismatch between the guiding layer and the substrate. A 45° polarization rotator becomes possible because the TE and TM mode degeneracy is nearly complete. A novel waveguide optical isolator using the 45° rotator is proposed.
