Abstract:
A strip of sacrificial semiconductor material is formed on top of a non-sacrificial semiconductor material substrate layer. A conformal layer of the non-sacrificial semiconductor material is epitaxially grown to cover the substrate layer and the strip of sacrificial semiconductor material. An etch is performed to selectively remove the strip of sacrificial semiconductor material and leave a hollow channel surrounded by the conformal layer and the substrate layer. Using an anneal, the conformal layer and the substrate layer are reflowed to produce an optical waveguide structure including the hollow channel.

Claim (Index 15):
An optical waveguide, comprising:\n a supporting semiconductor substrate having a top surface; and a layer of semiconductor material having a bottom surface in contact with the top surface of the supporting semiconductor substrate, said layer of semiconductor material including at least one hollow optical channel contained within the layer of semiconductor material and extending with a length parallel to the top surface of the supporting semiconductor substrate, said layer of semiconductor material further having a non-planar top surface including first top surface portions on either side of the at least one hollow optical channel and a second top surface extending over the at least one hollow optical channel, wherein a lowest portion of an inner surface of the at least one hollow optical channel is positioned below the first top surface portions of said layer of semiconductor material.
