Claim 7:
8. An optical system, comprising:
an active optical element that includes an active layer configured to convert electrical current to light or to convert light to electrical current; and
the spot-size converter of claim 1, the waveguide core clad by a multi-surfaced clad structure and optically coupled at the second end to the active layer of the active optical element, wherein at least one surface of the multi-surfaced clad structure is clad by air;
wherein at least one of a transverse dimension of the waveguide core or a lateral dimension of the waveguide core decreases along the waveguide axis from the second end toward the first end, the transverse and lateral dimensions at any point along the waveguide axis defining a plane that is normal to the waveguide axis.
