Abstract :
Post-growth energy band gap turning of the 980nm high power semiconductor laser structure through the quantum well intermixing (QWI) has been investigated. The QWI was carried out by depositing a thin film of SiO2 on top surface of the laser structure samples and followed by high temperature annealing. By using the QWI technique, band gap energy of the 980nm quantum well structure has been blue shifted up to >220nm. High quality of the laser diode structure after the QWI has been confirmed by fabricating the high performance semiconductor lasers using the wafer after the QWI.
