Abstract:
A device is provided for optical mode spot size conversion to optically couple a semiconductor waveguide with an optical fiber. The device includes a waveguide comprising a waveguide taper region, which comprises a shoulder portion and a ridge portion above the shoulder portion. The ridge portion has a width that tapers to meet a width of the shoulder portion. The waveguide taper region comprises a first material. The device also has a mode converter coupled to the waveguide. The mode converter includes a plurality of stages, and each of the plurality of stages tapers in a direction similar to a direction of taper of the waveguide taper region. The mode converter is made of a second material different from the first material.

Claim (Index 4):
The device of  claim 1 , wherein the waveguide further comprises a waveguide extension region coupled between the waveguide taper region and the mode converter, wherein:\n the waveguide extension region is made of the first material; the waveguide extension region has a thickness equal to a combined thickness of the shoulder portion and the ridge portion of the waveguide taper region; and the waveguide extension region and the shoulder portion of the waveguide taper region have a common width.
