摘要：

Mushroom structure vertical cavity surface emitting lasers with a 0.6-mu-m GaAs active layer sandwiched by two Al0.6Ga0.4As-Al0.08Ga0.92As multilayers as top and bottom mirrors exhibit 15 mA pulsed threshold current at 880 nm. Single longitudinal and single transverse mode operation was achieved on lasers with a 5-mu-m diameter active region at current levels near 2 x I(th). The light output above threshold current was linearly polarized with a polarization ratio of 25:1.
