Research Abstract

We have shown that magneto-optical properties can be controllably enhanced in molecular beam epitaxy (MBE) grown semiconductor-based multilayer structures consisting of a magnetic layer and GaAs/AlAs distributed Bragg reflectors (DBR), that is a one-dimensional semiconductor-based magneto-photonic crystal. Here, the magnetic layer is GaAs containing MnAs nanoscale clusters (GaAs:MnAs), which can be formed by annealing (GaMn)As alloys at 500 - 750℃. Structural and magneto-optical properties of GaAs:MnAs are presented and its dielectric functions are derived. It is shown that DBR/GaAs:MnAs/DBR structures were successfully grown by MBE and their magneto-optical effect is enhanced due to the localization of light at the Bragg wavelength. Comparison with theoretical calculations of the magneto-optical properties and device potentials are also clarified.
Furthermore, using the GaAs:MnAs nanocluster system, semiconductor-based waveguide-type optical isolators are proposed and analyzed. Our theoretical calculations have shown that both TE-mode and TM-mode operations can be realized.
