Abstract
An optical waveguide (OWG) consists of a substrate with a transparent thin layer (a few microns in thickness) on the top, through which layer a light wave can propagate. Since the light is confined to a small surface region of the OWG, the electric field associated with the light wave is very large at the surface of the OWG. Consequently, light absorption occurs significantly when suitable species, for example, dyes, are adsorbed onto the OWG surface. Thus, optical absorption by these species will be greatly enhanced by using OWGs.(1,2)
