Abstract
Abstract A channel waveguide structure comprises a substrate, a channel pattern defined in the substrate adjacent the top surface of the substrate, and a planar film layer on top substrate. The channel pattern comprises channels having a high index of refraction, while the film layer is made from a nonlinear organic material. In a preferred embodiment, the substrate is glass and the channel pattern comprises ion-exchanged channels. In this preferred embodiment, the nonlinear organic material is a soluble polydiacetylene, such as poly(3BCMU), poly(4BCMU), or poly(TS12). The thicknesses of the ion-exchanged channels and of the film layer can be adjusted so that the channel waveguide structure functions as a single mode waveguide for light having a wavelength in the range of 1.3 to 1.67 microns.
