Abstract
An integrated circuit may include at least one active optical device and a waveguide coupled thereto. The waveguide may include a superlattice including a plurality of stacked groups of layers. Each group of layers of the superlattice may include a plurality of stacked base semiconductor monolayers defining a base semiconductor portion and an energy band-modifying layer thereon. The energy-band modifying layer may include at least one non-semiconductor monolayer constrained within a crystal lattice of adjacent base semiconductor portions.
