Abstract :
V-grooved quantum wire (QWR) lasers were studied by near-field optical microscopy with 0.1 /spl mu/m spatial resolution. We mapped the electroluminescence from the quantum structures and measured the lasing mode evolution. Localized photocurrent measurements show spectral features consistent with the QWR lateral confinement.
