Abstract

Bi-substituted TbFe Garnet films grown by Liquid-Phase Epitaxial (LPE) method are demonstrated as a candidate for the temperature dependence free Faraday rotator in the telecom devices or the optical sensors applications. Several types of substituted GdGaGarnet (SGGG) substrates are applied in the tests. At X=0.48 o 0.56 in the Tb(3-X)BiXFe5O12, a series of very low temperature dependence garnet films are fabricated on the lattice constant of 12.465Å (GdCa)3(GaZrMg)5O12 substrates through the LPE-grown processing with optimized flux compositions. A couple of device applications are also demonstrated using these suppressed temperature dependence garnet films.
