Claim 10:
11. A monolithically formed laser and spot-size converter, comprising:
a laser that includes:
a substrate;
a lower cladding formed above the substrate;
an active layer formed above the lower cladding; and
an upper cladding formed above the active layer; and
the spot-size converter of claim 1, wherein the spot-size converter includes
the substrate,
wherein the first waveguide structure extends from the laser to a facet end, the first waveguide structure including the lower cladding and the upper cladding each extending continuously through the laser and the spot-size converter, and
wherein the second waveguide structure extends from the laser toward the facet end, the second waveguide structure including a waveguide core optically coupled to the active layer of the laser, wherein a cross-sectional area normal to the waveguide axis of the waveguide core decreases from the laser approaching the facet end.
