  • Abstract
    A new multiquantum barrier (MQB) to obtain a large potential cladding for visible AlGaInP lasers is proposed. The effective potential barrier enhanced by the MQB concept can be increased by constructing the MQB well layer with a smaller energy gap material rather than that of the active layer. Even for 600 nm range laser, the actual potential barrier height which electrons in the active layer feel under biased condition can be bigger than 200 meV.
