ASSIGNMENT OF ASSIGNORS INTEREST (SEE DOCUMENT FOR DETAILS). Request PDF Wideband nonmagnetic linear optical isolator in thin-film lithium niobate We introduce a new class of wideband and integrated nonmagnetic linear optical isolators based on. In the market today, isolation devices based on optical technology (optocouplers) are still mainly. The isolator comprises a polarizing film provided on each of light incidence and outgoing surfaces, a Faraday device (1) for rotating 45° the plane of polarization of incident light, and a magnetic member (3) for applying a magnetic field to the Faraday device. reassignment HUAWEI TECHNOLOGIES CO., LTD. A small and lightweight optical isolator which can be produced at a low cost through a simple process.
