LONG RANGE SURFACE PLASMON OPTICAL WAVEGUIDE SENSORS HAVING DOUBLE METAL LAYERS

摘要

The present invention relates to a long-range surface plasmon optical waveguide sensors, more specifically, to a substrate, dielectric layer above substrate, it positioned at the thin metal film of dielectric layer, is formed on metallic film, sample is an auxiliary queue layer, it includes the third dielectric layer and metal for being located in bell band that wherein metal, which is located at auxiliary queue layer to be formed will pass through a predetermined channel-sensor unit,; Metallic film and metal-light source are used to induce a surface plasmon between band; It is related to a long-range surface plasmon optical waveguide sensor, has a; Detection section is changed for detecting and analyzing light according to surface plasmon. ;Wherein sensor is that propagation loss, susceptibility and high detection limit are small, fast analysis speed can be in different sizes, such as small or Lightweight System, DNA chip, a biochip manufacture, such as protein-chip, immune sensor, one rare earth elemental analysis sensor, a gas analysis it be applied to various fields, such as sensor. ;Optical sensor, surface plasmon optical waveguide biosensor, gas sensor
