THIN-FILM MAGNETO-OPTIC POLARIZATION ROTATOR. |
摘要 |
In a polarization rotator device, a thin-film magneto-optic medium is magnetized by a thin-film magnet. To serve as an optical isolator, the device may include polarizers. In such an optical isolator, in which the magneto-optic medium was formed as a Bi-YIG triple-layer structure, and the thin-film magnet as a single-crystal iron-cobalt layer, an extinction ratio better than -20 dB was realized. |
