Abstract:
A spot-size converter having a waveguiding structure. The first part of the waveguiding structure receives light from or transmits light to a first waveguide in a first propagation mode. The first part of the waveguiding structure has a longitudinally varying effective refractive index that decreases away from the first waveguide. The second part of the waveguiding structure transmits light to or receives light from a second waveguide in a second propagation mode. The second part of the waveguiding structure has a number of high-index elements arranged in a single plane, extending along a longitudinal waveguiding axis and at least partially overlapping the first part of the waveguiding structure. The first propagation mode of the first waveguide progressively transforms into the second propagation mode of the second waveguide along the longitudinal waveguiding axis through an overlap region between the first part and the second part of the waveguiding structure.

Claim (Index 33):
A silicon photonic spot-size converter comprising:\n a silicon substrate; an insulating layer formed on the silicon substrate; a silicon core formed on the insulating layer and coupled to a first waveguide to receive light from or transmit light to the first waveguide in a first propagation mode, the silicon core being characterized by a longitudinally varying effective refractive index that decreases away from the first waveguide; and a plurality of high-index rods coupled to a second waveguide to transmit light to or receive light from the second waveguide in a second propagation mode, the plurality of high-index rods arranged in a single plane, extending along a longitudinal waveguiding axis and partially overlapping the silicon core, wherein the first propagation mode of the first waveguide progressively transforms into the second propagation mode of the second waveguide.
