We mapped the 3D dispersion relation of surface plasmon resonance (SPR) in a nanodevice using a novel far-field method. This technique reveals anisotropic interactions and provides detailed spectroscopic responses for SPR.

Area of Science:

  • Optoelectronics
  • Nanophotonics
  • Condensed Matter Physics

Background:

  • Surface plasmon resonance (SPR) is crucial for sensing and optoelectronic devices.
  • Understanding the full 3D dispersion relation of SPR is essential for optimizing nanodevice performance.
  • Current methods for characterizing SPR dispersion are often limited in scope or resolution.

Purpose of the Study:

  • To present far-field measurements of the complete 3D dispersion relation of SPR in an integrated quantum well nanodevice.
  • To introduce and validate a novel experimental method for direct mapping of electromagnetic (EM) wave dispersion.
  • To demonstrate the capability of the method for tracking SPR peak surfaces and revealing anisotropic interactions.

Main Methods:

  • Far-field measurements utilizing a grating to extract surface plasmons.
