基于双面金属波导的纳米磁流体磁调制
Magnetic modulation of magnetic-fluid based on the symmetrical metal-cladding optical waveguide
摘要
Abstract
A new type of symmetrical metal-cladding optical waveguide structures is proposed. The guiding layer that supports the oscillating field is submillimeter scale and severs as the sample room. The water-based Fe3O4 magnetic fluid with a volume fraction of 0. 15% is injected into the sample room. The ultrahigh order modes are excited by a 860 run laser beam on the structure with small incident angle ( <5). Owing to the strong concentration of the magnetic field, the sensitivity of the ultrahigh-order modes is very high. The rise and fall time of magnetic fluid is 2 ms when 10 mT magnetic field is applied.关键词
