چکیده
|
We theoretically investigated an enhancement of the magneto-optical faraday rotations along with large transmittance in two multilayer structures. the shifts of the faraday rotation peaks are more obvious than the transmittance peaks when the grating period is changed, which is beneficial to acquire the large faraday rotation and transmittance. the faraday rotation of tri-layer system is five times larger than the bilayer system, and the faraday resonance peak can be mediated by changing the refractive index or thickness of the additional nonmagnetic dielectric layer (ndl) layer. these results are important for applications in highly integrated optoelectronic and magneto-optical devices.
