| 摘要 |
A waveguide for guiding electromagnetic radiation of a given range of wavelengths includes a transparent substrate made from non-polymer material, preferably glass, into which at least one elongated channel is etched. A polymer material with a higher refractive index than that of the substrate is deposited within, and extends along, the channel, so as to define a waveguide. The regions of the substrate adjacent to the ends of the channel are preferably treated, such as by ion-exchange, to form secondary waveguide portions, optically coupled to the polymer waveguide, for input and output optical coupling with the waveguide. Also disclosed is a production method for such waveguides.
