  • Abstract
    The first electrically-pumped GaSb-based vertical cavity surface emitting lasers emitting above 2.5 mum at room temperature are reported. This monolithic all-epitaxial structure is composed of two n-doped AlAsSb/GaSb DBRs, a type-I GaInAsSb/AlGaAsSb multi-quantum-well active region and an InAsSb/GaSb tunnel junction. Devices with a diameter of 30 mum operate in quasi-CW (1 mus, 5) at 2.52 mum above 300 K. A minimum threshold current of 4.7 kA/cm2 in pulsed operation (100 ns, 0.5) was obtained at 251 K with these devices.
