Method for making an integrated circuit comprising an active optical device having an energy band engineered superlattice

摘要

A method for making an integrated circuit may include forming at least one active optical device including 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. The method may further include forming a waveguide coupled to the at least one active optical device.
