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 techniques for the integration of devices based in InP/InGaAs
materials system and InGaAs quantum dots will be discussed.
