ABSTRACT:
An optical device having an optical circuit integrated on a side of a substrate having a column of substrate material. The column of substrate material preferably includes a cylindrical portion having a circular cross-section. The optical device preferably includes an optical waveguide that is wound around the cylindrical portion of the substrate. The waveguide is defined by a core region in a layer of optically transparent material on the side of the column. The core region can be generated by altering the index of refraction of the transparent material. The core region can also be generated by depositing a patterned layer of a second optically transparent material. The optical device can also include active devices such as fiber amplifiers, semiconductor lasers, and optical sampling devices. The optical device is preferably constructed by rotating the substrate while depositing optically transparent materials and/or various semiconductor materials on the substrate.
