Abstract
The present disclosure relates to an electromagnetic energy detector. The detector can include a substrate having a first refractive index; a metal layer; an absorber layer having a second refractive index and disposed between the substrate and the metal layer; a coupling structure to convert incident radiation to a surface plasma wave; additional conducting layers to provide for electrical contact to the electromagnetic energy detector, each conducting layer characterized by a conductivity and a refractive index; and a surface plasma wave (“SPW”) mode-confining layer having a third refractive index that is higher than the second refractive index disposed between the substrate and the metal layer.
