HIGH RESOLUTION SURFACE PLASMON RESONANCE SENSOR AND SENSOR SYSTEM THEREOF

摘要

Provided is a surface plasmon resonance sensor including: a part of delivering light by which a signal beam is incident to generate an evanescent field; and a part of exciting surface plasmon for exciting surface plasmons by the generated evanescent field and giving rise to a surface plasmon resonance, wherein a dielectric waveguide layer is inserted between metal layers of the part of exciting surface plasmon, and surface plasmon resonance properties are changed by an object to be analyzed.
