Demonstration of a DFB laser with an integrated electro-absorption modulator produced using a novel quantum-well intermixing technique

Bandgap engineering is used extensively in the telecommunications field. Quantum well intermixing (QWI) is a post-growth method of bandgap engineering that has been studied for the integration of photonic devices (Marsh et al., J. Vac. Sci. Technol. A16 (1998) 810). A novel method of QWI has been discovered that uses layers of indium phosphide grown by helium-plasma-assisted gas source molecular beam epitaxy, subsequently referred to as …
