ABSTRACT:
A first core layer and a second core layer, serving as optical waveguides, whose refractive indexes are greater than that of a substrate are placed on the surface of the substrate that functions as a cladding layer. An interval between the first core layer and the second core layer is partially narrowed so that lightwaves progressing through these core layers may develop an optical mode coupling. Disposed in this optical mode coupling area is a detector, which comes in contact with liquid or gas and interacts with a substance to be detected, such as chemical or biological substance. A receptor material which selectively captures the substance to be detected is fixed on a surface of the detector. Antibody, enzyme, cell, ionophore, single-strand DNA and the like are examples of the receptor material.
