ABSTRACT:
An analytical system uses a waveguide having embedded Bragg gratings to redirect light from the waveguide outwardly for analytical determination by detectors. The analytical system can be a spectrophotometer, spectrofluorimeter, or other means for analyzing the components of light passed through a sample or emanating from a sample. The system can be single or multi-channeled and can be integrated with a detector onto a single chip device. A manifold with multiple input waveguides and multiple output waveguides is also provided. The interaction point between the input and output waveguides is a target area in which a sample capillary tube can be located.
