Channel waveguides and their applications

摘要

The present invention relates to integrated optical channel waveguides and their applications as switches, modulators and sensors.;The channel waveguide has the shape of a channel-like structure located within or over the planar substrate material and narrowed geometrically narrowly, and the confinement is positioned perpendicular to the propagation direction of the light.;A single mode integrated optical broadband channel waveguide has been described which can deliver light from the entire visible wavelength range, for example a single mode, which is effective, i.e. with low light attenuation, . If necessary, the light can be converted or modulated in a wavelength-dependent or wavelength-independent manner, for example, by means of electro-optical means.;The channel waveguide is basically manufactured by means of known processes, for example refractive index change.
