Abstract:
An apparatus includes an optical rib waveguide on a substrate, the optical rib waveguide further includes: a slab layer of silicon, a shallow rib of silicon in height that tapers laterally along a taper region, a deep rib of silicon that meets the shallow rib along the taper region of the shallow rib, and wherein the deep rib and the shallow rib have a same width, and wherein the shallow rib has a greater height than the deep rib, a core of silicon that tapers laterally in a range of 50-90% and extends on top of the deep rib and the shallow rib, and a cladding layer of silicon oxide that covers the slab, core, deep rib, and shallow rib.

Claim (Index 5):
A method comprising:\n generating light; confining the light within a waveguide, the waveguide comprising:\n a slab layer of silicon; \n a shallow rib of silicon in height that tapers laterally along a taper region; \n a deep rib of silicon that meets the shallow rib along the taper region of the shallow rib, wherein the slab layer borders the shallow rib and the deep rib, \n wherein the deep rib and the shallow rib have a same width, and \n wherein the shallow rib has a greater height than the deep rib; \n a core of silicon that tapers laterally in a range of 50-90% and extends on top of the deep rib and the shallow rib; and \n a cladding layer of silicon oxide that covers the slab, core, deep rib, and shallow rib.
