IEEE LEOS Distinguished Lecturer,
Integration of optoelectronic devices is of current interest due to its application in communication systems for the fabrication of wavelength division multiplexing (WDM) sources and photonic integrated circuits (PICs). Quantum well intermixing is an enabling technology for the integration of optoelectronic devices. In this talk, I will review various quantum well intermixing techniques and their suitability for various applications. Main techniques covered are impurity free disordering and implantation induced disordering. Results on multi-wavelength lasers and quantum well infrared photodetectors based on GaAs/AlGaAs/InGaAs material system will be presented. Potential of these technique for the integration of devices based in InP/InGaAs materials system and InGaAs quantum dots will be discussed.
