Abstract:
A self-sanitizing surface structure configured to selectively refract light, a method of fabricating a self-sanitizing surface configured to selectively refract light, and a method of decontaminating a surface using selectively refracted light. A waveguide including a support layer below a propagating layer is positioned over a substrate as a self-sanitizing layer. In the absence of a contaminant or residue on the waveguide, UV light injected into the propagating layer is constrained within the propagating layer due to total internal reflection. When a residue is present on the self-sanitizing surface structure, light may be selectively refracted at or near the interface with the residue along the side of the waveguide to destroy the residue. The self-sanitizing surface structure may be configured to refract a suitable amount of UV light in response to a particular type of residue or application.

Claim (Index 7):
The self-sanitizing surface structure of  claim 1 , further comprising:\n an ultraviolet (UV) light source for generating UV light; and optics to direct the UV light into the propagating layer, the optics being directly coupled to an end of the propagating layer perpendicular to the first and second transverse sides.
