Brief
This article reviews the recent advancements in magneto-optical (MO) devices used in high-capacity and intelligent optical networks, highlighting their crucial role and future development towards cost-effective metropolitan, FTTH, and next-generation peta-bit and all-optical communication systems, while also noting the future need for MO-based polarization and dispersion control.
Summary
This review paper discusses the recent progress in magneto-optical (MO) devices and their applications in modern optical networks. MO devices, initially used in polarization-dependent isolators, have become crucial for large-capacity and flexible optical networks due to the development of polarization-independent and variable devices like optical isolators, attenuators, gain equalizers, circulators, and interleavers. The paper highlights the increasing demand for cost-effective MO devices in metropolitan and FTTH networks and anticipates the need for MO-based polarization and dispersion control in future peta-bit and all-optical communication systems.
