Solid source molecular beam epitaxy of low thresholdstrained layer 1.3 µm InAsP/GaInAsP lasers

Abstract
A threshold current density of 270 A/cm2 has been achieved for 2 mm long broad area lasers grown by solid source molecular beam epitaxy. These are the lowest reported threshold current density 1.3 µm lasers by any type of MBE growth technique.
