| Popis: | The dysprosium substituted yttrium iron garnet (Dy:YIG) film was investigated because of high magnetstriction for operating voltage driven type magneto-optic spatial light modulators (V-MOSLMs). The fabricated Dy:YIG film had magnetostriction of 3.5 ppm, soft magnetic property, transmittance of 47 % and faraday rotation of -2.7 deg./μm at 532 nm wavelength. Furthermore, a reflection type one dimensional magneto photonic crystal (1D-MPC) by using the Dy:YIG film as a defect layer was fabricated for enhancement of Kerr rotation. In the case of the defect layer of 147 nm thick, a Kerr rotation angle was 15 times higher than the single layer at localized wavelength. |
