Transverse Kerr effect in magnetic (Ga, Mn)As-based semiconductors and its applicability in waveguide isolators

Popis výsledku v původním jazyce

We report on the measurement of transverse Kerr effect in a diluted magnetic semiconductor Ga1-xMnxAs in visible and near infra-red spectral ranges. The relative change of reflectivity upon the change of the magnetization orientation is as large as 2%, the same order of magnitude as the response of ferromagnetic metals in the visible light. The experimental data are modeled by theoretical calculations, showing a very good match between the theory and the experiment. We further use the theoretical model in order to predict nonreciprocal losses in a planar waveguide. The predicted nonreciprocal losses are an order of magnitude larger as compared to devices with a Co/Fe ferromagnetic layer reported so far. Published by AIP Publishing.
