A new structural waveguide, which is referred to as a channel–planar composite optical waveguide (COWG), has been fabricated by sputtering of a titanium dioxide (TiO>2) film onto a glass substrate with potassium ion-exchanged channel waveguides. By use of a mask during deposition, the TiO2 film was formed into a 27-nm-thick, 5-mm-wide strip with two 1-mm-long tapered ends perpendicular to the channel waveguides. Adiabatic transition of the TE00 mode and the TE00– TM00 mode separation inside such a channel–planar COWG were demonstrated by combination of theoretical analysis and measurement of the experimental attenuation that arises from scattering loss and evanescent-field dye absorption. Changing the superstrate index in the region of the TiO2 film in the channel–planar COWG yielded polarimetric interference patterns. This new technique can be applied to integrated optical chemical and biological sensors to produce enhanced sensitivity.
