Patent ID: 8263001

Claim:
An integrated bio-chip comprising: a substrate including one or more reaction regions on which samples are disposed; and one or more excitation light absorbing waveguides disposed in the substrate, wherein a first end portion of each of the one or more excitation light absorbing waveguides is exposed from the substrate at an upper surface thereof, a second end portion of each of the one or more excitation light absorbing waveguides is exposed from the substrate at a lower surface thereof, the one or more reaction regions are disposed at the upper surface of the substrate, and each of the one or more excitation light absorbing waveguides includes a color filter core which transmits fluorescent light emitted from the samples and absorbs excitation light which excites the samples, wherein each of the one or more excitation light absorbing waveguides is disposed in a through hole in the substrate that extends from the upper surface to the lower surface, and wherein the upper and lower surfaces define opposite major surface planes defining the substrate.
