Wideband integrated multiple laser chip on 1.55 /spl mu/m heterostructure using controlled bandgap tuning by quantum well intermixing

摘要

Summary form only given. Quantum well intermixing (QWI) is a key technology for the fabrication of advanced photonic integrated components (PICs) requiring integration of multiple bandgap values over a 150 nm range on a single substrate. Standard MOCVD-grown, 1.55 /spl mu/m heterostructures with five quantum wells were used for this work.
