Rainbow trapping stores broadband light in metamaterials. Metal-insulator-metal tapers are ideal for this light trapping, acting as optical cavities with high quality factors.

Area of Science:

  • Optics and Photonics
  • Materials Science
  • Nanotechnology

Background:

  • Rainbow trapping is a proposed method for localized storage of broadband electromagnetic radiation.

  • Tapered waveguide structures with dielectric cores and metal cladding are best suited for light trapping.
  • A metal-insulator-metal taper functions as a cascade of optical cavities with distinct resonant frequencies.
  • These structures exhibit high quality factors and small effective volumes, comparable to traditional plasmonic resonators.

Conclusions:

  • Metal-insulator-metal tapers provide an effective platform for rainbow trapping.
  • The demonstrated structures offer efficient localized storage of broadband electromagnetic radiation.
  • This work advances the understanding and design of metamaterials for optical applications.
