| Outline of Final Research Achievements |
We fabricated magneto-optical (MO) devices with a magnetic media distributing on the wide side of optical fiber, and developed the polarization control devices using the spin of magnetic media. We clarified that the local modulation of magnetization of magnetic media on the multi-mode fiber generates mode-selective MO signals among the multiplexed light propagating in the core, and also that the MO signal can be spatially demultiplexed.
Further, we evaluate MO effect on the evanescent wave using samples with multi-layer structures, and shows that the evanescent wave enhance the MO effect and its MO figure of merit.
