Abstract
The invention pertains to a polymeric optical waveguide device, such as an optical switch, splitter, phased array, Mach Zehnder interferometer, or the like, comprising at least one polymer waveguide channel embedded in a polymer cladding, said waveguide channel having a refractive index higher than that of the cladding and comprising at least one bend or curved section at least part of which has a refractive index contrast higher than that in the rest of the waveguide channel. The devices according to the invention are relatively compact.
