Abstract
An integrated bio-chip includes a substrate and one or more excitation light absorbing waveguides disposed in the substrate. The substrate includes one or more reaction regions on which samples are disposed. An end portion of each of the one or more excitation light absorbing waveguides is exposed from the substrate at an upper surface thereof, another end portion of each of the one or more excitation light absorbing waveguides is exposed from the substrate at a lower surface thereof, and the one or more reaction regions are disposed at a upper surface of the substrate. The one or more excitation light absorbing waveguides absorbs excitation light incident to the samples, and transmits fluorescent light emitted from the samples.
