Abstract
A method of forming a silicon based optical waveguide can include forming a silicon-on-insulator structure including a non-crystalline silicon portion and a single crystalline silicon portion of an active silicon layer in the structure. The non-crystalline silicon portion can be replaced with an amorphous silicon portion and maintaining the single crystalline silicon portion and the amorphous portion can be crystallized using the single crystalline silicon portion as a seed to form a laterally grown single crystalline silicon portion including the amorphous and single crystalline silicon portions.
