| 摘 要： | 利用一种样品空间层达亚毫米尺度的双面金属波导,将磁流体注入波导样品空间层作为导波层来研究磁流体的窄带滤波特性.首先将波长为l 550 nm的激光入射到波导表面,选择合适的入射光导模共振角,激发波导中的超高阶导模,使磁流体处于光波导的振荡场中；然后,应用超高阶导模的高灵敏度特点,将磁场施加在波导上改变磁流体的折射率,使波...

| Abstract: | A type of ultrathick double metal cladding optical waveguide with a submillimeter scale was used to investigate the narrow bandwidth filter of magnetic fluid,in which the magnetic fluid were injected into the sample as a guided layer.While the 1 550 nm laser beam was incident on the waveguide with resonance angle,ultrahigh order modes would be excited;the magnetic fluid was in the oscillating field.Then based on ultrahigh order modes,the refractive index of magnetic fluid was changed owing to the strong con... |
