High-Performance Optical Isolators

This kind of product, made of high-performance material of Sm2Co17, is mainly applied in optical isolators, following accuracy abrasive lapping process.

SmCo micro magnets were used for integrated biasing magnets. They were deposited on top of claddings of both magnesium oxide and yttrium oxide, all using the same sputtering system that was used to deposit the garnet films. These magnetic films had high enough remanence fields to saturate the garnet waveguides.
