چکیده
A new method to achieve period: c reversal a of magnetization, necessaryto attain high mode conversion effIc.'encles In magneto-optic waveguides,is described. It la accomplished by .neans of a periodic permalloystructure overlaying the optical procuration path. With proper biasfields, we have observed an optimum Do conversion efficiency of (80 ±2)%at 1.15 pm in a Gd ,.Ga iron garnet film guide.

Integrated thin-film lithium niobate platform has recently emerged as a promising candidate for next-generation, high-efficiency wavelength conversion systems that allow dense packaging and mass-production. Here we demonstrate efficient, phase-matched second harmonic generation in lithographically-defined thin-film lithium niobate waveguides with sub-micron dimensions. Both modal phase matching...
متن کاملGarnet-to-perovskite transition in Gd3Sc2Ga3O12 at high pressure and high temperature.
The structural phase transition of gadolinium-scandium-gallium garnet (Gd(3)Sc(2)Ga(3)O(12), GSGG) has been studied at high pressure and high temperature using the synchrotron X-ray diffraction technique in a laser-heated diamond anvil cell. The GSGG garnet transformed to an orthorhombic perovskite structure at approximately 24 GPa after laser heating to 1500-2000 K. The garnet-to-perovskite ph...

We report on our progress towards the integration of nonreciprocal optical elements in, for example, an integrated optical waveguide isolator on conventional semiconductor photonic platforms. Our approach uses an evanescent interaction with a magneto-optic iron garnet upper cladding. Specifically, ceriumand bismuthsubstituted yttrium and terbium iron garnets were investigated. Device fabricatio...
متن کاملGeometry Induced Magneto-optic Effects in Lpe Grown Magnetic Garnet Films
This dissertation addresses dimensionality-induced magneto-optic effects in liquid-phaseepitaxy magnetic garnet thin films. It is found that the Faraday rotation (FR) per unit length evinces a marked and steady enhancement as the film thickness is reduced below ~100 nm in Bi0.8Gd0.2Lu2Fe5O12, although it remains constant in the micronand most of the submicron-regime. The reported specific FR ch...
