Quantum wells intermixing in InGaAsP/InGaAsP Laser Structure for Photonic Integrated Circuits

摘要

We report the selective area bandgap tuning of multiple quantum well structures by an impurity free vacancy induced quantum well intermixing technique. A 3dB waveguide directional coupler was fabricated in the disordered section of an intermixed quantum well sample as a demonstration of photonic device applications.
