Difracción de Bragg de ondas ópticas guiadas por ondas de dipolo de spin en guías de onda ferromagnéticas de doble capa

Cortés-Pérez, O.; Ordoñez-Romero, C.L.; Ortega-Martínez, R.; Kolokoltsev, O.V.; Grishin, A.

Resumen en español Las peculiaridades de la difracción de Bragg de ondas ópticas guiadas (Optical Guided Waves o OGW) por ondas de dipolo de spin (Spin Dipole Waves o SDW) en una heteroestructura de ferrita, basada en una película delgada de Bi3Fe5O12(BIG) depositada en una muestra estándar de YIG/GGG (una película delgada de granate de hierro e itrio sobre un sustrato de granate de galio y gadolinio). Se muestra que la eficiencia de interacción entre ondas OGW y SDW en BIG/YIG/GGG pu (mas) ede ser de 4 a 30 veces más grande que la eficiencia en una guía de onda estándar de YIG/GGG, aun en este caso cuando las ondas que interactúan están localizadas en la guía de onda de YIG. Resumen en inglés The peculiarities of the Bragg diffraction of optical guided waves (OGWs) by spin-dipole waves (SDWs) in a new ferrite heterostructure, based on Bi3Fe5O12(BIG) thin film deposited on a standard YIG/GGG (a Yttrium Iron Garnet thin film over a Galium Gadolinum Garnet substrate) sample, is presented. It is shown that the efficiency of waveguide magnetooptic interaction between OGWs and SDWs in BIG/YIG/GGG can be 4-14 times larger than in the standard YIG/GGG waveguide, even in the case when the interacting waves are localized in YIG waveguide layer.
