A material analysis for the construction of the filter is performed, and the behavior of the filter is investigated for the most promising magneto-optical materials. It is shown that bandwidths in the range of a few nanometers to tens of nanometers may be achieved depending on the material used in the filter construction 关键词: band-pass filters;cadmium compounds;Faraday effect;garnets;magneto-optical devices;manganese compounds;optical filters;semimagnetic semiconductors;magneto-optical bandpass filter;tunable bandpass filter;Faraday rotators;polarizers;material analysis;bandwidths;rare earth garnets;semimagnetic semiconductors;Cd1-xMnxTe;620 to 1000 nm;CdMnTe;TbGG;TbGa5O12
