基于双面金属包覆介质波导灵敏度的研究
Study on the Sensitivity of Symmetrical Metal-Cladding Dielectric Waveguide
摘要
Abstract
By applying the perturbation approximation method to dispersion equation of symmetrical metal-Cladding dielectric medium waveguide, the author finds that when the thickness of waveguide layer decreases to sub millimeter range, the effective index will approach zero, and the ultrahigh-order modes are no longer related to polarization. Then the author defines the sensitivity of waveguide,and gets its relationship with effective index,thickness,wavelength and dielectric constant. When the effective index approaches zero, the ultrahigh-order modes will have a super high sensitivity. This theory is of certain directive significance to biosensor and photoelectronic device.关键词
