Research Abstract

We have done research on novel magneto-optic materials and amplifying optical isolators, based on conventional semiconductor optical isolators. We have developed semiconductor optical isolators using epitaxial ferromagnetic metal MnSb and realized an extinction ratio of 12.3 dB/mm and optical isolator operation at 70 ℃. Magneto-optic figure of merit of novel magneto-optic materials (TiO 2 :Co and PrCoB) was investigated. Furthermore, we have realized amplifying semiconductor optical isolators. These research results are useful for optical isolators integrated with semiconductor lasers and their application to optical information signal processing.
