Abstract:
1. An optical waveguide, comprising: a substrate; a first layer with a first refractive index formed directly on top of the substrate; and a waveguide structure formed directly on top of the first layer, wherein the waveguide structure includes a waveguide layer which includes ZnS—SiO wherein a light beam coupled into the waveguide layer is guided within the waveguide layer such that the light beam travels along a predefined path volume formed by the waveguide layer, and wherein the first layer has a first absorption coefficient with respect to a wavelength of light guidable in the waveguide layer, and the substrate has a second absorption coefficient with respect to the wavelength of light guidable in the waveguide layer, the first absorption coefficient being less than the second absorption coefficient.
