    摘要: A channel waveguide structure which can be incorporated into VLSI (very large scale integration) integrated circuits uses a SiGe (silicon germanium) alloy core and Si (silicon) top and bottom cladding layers. The core may consist of only a SiGe alloy layer or it may be formed as a superlattice containing Si layers alternating with SiGe alloy layers. LOCOS (locally oxidized silicon) regions are formed on the top cladding layer at spaced locations thereby defining lateral boundaries of channels in the core.

    摘要: A method and apparatus are provided for coupling light from a fiber to a waveguide on an OEIC (optoelectronic integrated circuit). The region of the fiber to be connected is made into a D-fiber by removing a portion of its cladding. The flat surface is fused to a silicon dioxide coated portion of the waveguide. The light in the fiber is evanescently coupled into the waveguide on the OEIC which is typically a planar or channel waveguide.
