PLANAR OPTICAL WAVEGUIDE WITH CORE OF LOW-INDEX-OF-REFRACTION INTERROGATION MEDIUM
First Claim
1. An apparatus for illuminating a sample, the apparatus comprising:
- a waveguide includinga first substrate including a first outer surface and a first inner surface, anda second substrate including a second outer surface and a second inner surface, the first and second inner surfaces of the first and second substrates, respectively, being spaced apart from each other and partly defining a volume for confining the sample therein; and
a light source for providing light directed toward the waveguide such that the light is optically coupled to and contained within the waveguide between the outer surfaces of the first and second substrates, while illuminating at least a portion of the sample confined within the volume.

Abstract
An apparatus for illuminating a sample includes a planar waveguide. The planar waveguide includes a first substrate, including a first outer surface and a first inner surface, and a second substrate, including a second outer surface and a second inner surface. The first and second inner surfaces of the first and second substrates, respectively, are spaced apart from each other and partly define a volume for confining the sample therein. The apparatus also includes a light source for providing light directed toward the planar waveguide, such that the light is optically coupled to and contained within the planar waveguide between the outer surfaces of the first and second substrates, while illuminating at least a portion of the sample confined within the volume.
