Abstract
Apparatus, methods, and hollow metal waveguides to perform surface-enhanced Raman spectroscopy are disclosed. An example apparatus includes a hollow metal waveguide to direct Raman photons from an intermediate location within a volume of the hollow metal waveguide toward a distal end of the hollow metal waveguide, and a mirror to direct incident light from a light source to the intermediate location within the volume of the hollow metal waveguide and to direct at least some of the Raman photons toward the distal end.

An apparatus, comprising:
- a hollow metal waveguide to direct Raman photons from an intermediate location within a volume of the hollow metal waveguide toward a distal end of the hollow metal waveguide;
- and
- a mirror to direct incident light from a light source to the intermediate location within the volume of the hollow metal waveguide and to direct at least some of the Raman photons toward the distal end.
A method, comprising:
- applying incident light at a first frequency to an intermediate location within a hollow metal waveguide via a mirror disposed in the hollow metal waveguide, the hollow metal waveguide to direct Raman photons from the intermediate location toward a distal end of the hollow metal waveguide and to reflect Raman photons toward the distal end;
- and
- collecting the Raman photons at the distal end of the hollow metal waveguide.
A horn-shaped hollow metal waveguide, comprising a first opening at a proximal end to receive incident light and a second opening at a distal end to provide Raman photons to a spectrometer, and shaped to direct the incident light toward an intermediate location in the hollow metal waveguide and to direct the Raman photons from the intermediate location to the distal end.
