Abstract
A tapered waveguide. In some embodiments, the waveguide has a narrow end and a wide end. A taper angle of the waveguide may be, at each point along the waveguide, less than an adiabatic taper angle by a margin. The margin may be greater at a first point than at a second point, where the adiabatic taper angle is less at the first point than at the second point.
