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).
