Monolithic Magneto-Optical Isolator Achieved with Nanocomposite Garnet in Silicon Photonics
By
Taichi Goto
Summary
This article presents a research breakthrough in silicon photonics: a monolithically integrated magneto-optical (MO) isolator using a nanocomposite garnet material within an asymmetric Mach–Zehnder interferometer design. The device achieves 4.4 dB of MO isolation, addressing a critical challenge in photonic integrated circuits (PICs) where back-reflections degrade performance. The work is significant for advancing silicon-based PICs and copackaged optics (CPO) technology, which merges electronic and optical circuits on a single platform for next-generation computing and data communication.
