Abstract: In accordance with the invention, increased maximum modulation speeds and improved hole distribution are obtained for light emitting devices. Barrier layers of a quantum well structure for a light emitting device are formed with varying barrier energy heights. Quantum well layers of the quantum well structure are formed between the barrier layers.

Abstract: Embodiments of the invention involve a monolithic vertical configuration for coupling a ring resonator and a bus waveguides. The monolithic vertical coupling arrangement, with the epitaxial grown coupling between the waveguide and the resonator, provides control of the coupling coefficient. The vertical coupling arrangement allows for different material compositions in the waveguide and resonator structures, e.g. active quantum well resonators and transparent waveguides, to facilitate the design of active WDM components.
