Abstract
Provided are spectrometers utilizing surface plasmons and surface plasmon resonance. The spectrometer includes a substrate including a region having a permittivity slope (varying permittivity), a dielectric spacer configured to correspond to the region having a permittivity slope, and a detector configured to face the region having a permittivity slope with the dielectric spacer therebetween. The region having a permittivity slope includes a region having a dopant concentration slope (varying concentration).
Claims16
A spectrometer utilizing surface plasmon resonance, the spectrometer comprising:
- a substrate comprising a region having a permittivity slope;
- a dielectric spacer configured to correspond to the region having the permittivity slope;
- and
- a detector configured to face the region having the permittivity slope with the dielectric spacer therebetween.
A spectrometer utilizing surface plasmon resonance, the spectrometer comprising:
- a substrate comprising a first region having a varying permittivity, wherein the varying permittivity varies from a first permittivity to a second permittivity in the first region;
- a detector adjacent to and facing the first region;
- a dielectric spacer positioned between the substrate and the detector, the dielectric spacer having a dimension corresponding to at least a dimension of the region having the varying permittivity.
