    摘要： In one aspect the invention provides a graded refractive index single crystal waveguide having a glass block containing at least one crystal core, the crystal core having a central portion extending along an axis from a first end to a second end; an interface defining a peripheral boundary of the crystal core at a junction of the crystal core and an adjacent portion of the glass block, and a continuous, radially symmetric misorientation transverse to the central portion; wherein the misorientation has a misorientation angle that increases with increasing distance from the central portion towards the interface.

    摘要： The present invention includes methods of promoting single crystal growth via solid-solid transformation of an appropriate glass, while avoiding the gaseous or liquid phase. In certain embodiments, in the all-solid-state glass-to-crystal transformation of the invention, extraneous nucleation is avoided relative to crystal growth via spatially localized laser heating and optional inclusion of a suitable glass former in the composition. The ability to fabricate patterned single-crystal architecture on a glass surface was demonstrated, providing a new class of micro-structured substrate for low cost epitaxial growth and active planar devices, for example.
