Abstract
A high-index-contrast waveguide structure material used to guide light through a low-refractive-index material. In one embodiment, the waveguide structures are capable of guiding and confining light in such a way that very high optical intensity is obtained in a small cross-sectional area or gap filled with any material with sufficiently low refractive index, relative to the remainder of the structure. The structure may be used to form resonators, optical couplers, directional optical couplers and other optical devices. Structures may be formed consistent with integrated circuit forming processes.
