Orientation dependent emission properties of columnar quantum dash laser structures
S. Hein, P. Podemski, G. Sek, J. Misiewicz, P. Ridha et al.
InAs columnar quantum dash (CQDash) structures on (100) InP have been realized by gas source molecular beam epitaxy for stacking numbers of up to 24. Laser devices show low threshold current densities between 0.73 and 3.5 kA/cm, dependent on the CQDash orientation within the cavity. Photoluminescen ... [Appl. Phys.
