Abstract
|
Transmittance and Faraday rotation(FR) spectra of one-dimensionalmagneticheterostructures are investigated using 4 by 4 transfer matrix method. It is revealed that in a simple magnetic heterostructure the enhanced FR at a desired wavelength can be realized considering a special design of substructures and adjusting the thicknesses of constituent magnetic layers. In addition, a complex magnetic heterostructure with capability of providing the multichannel enhanced FRs at desired wavelengths is introduced. It is shown that such a heterostructure could support high transmittance enhanced FRs at telecommunication wavelengths of 1300 and 1550 nm, simultaneously. The results may have potential applications in designing the multi-function single magneto-optical devices such as multichannel Faraday rotators and wavelength division multiplexing systems.
