Abstract
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.
