圣巴巴拉加州大学小组发展了第一个室温运转、输出波长 1.55μm的电抽运、全晶格匹配、砷锑化物单块垂直腔激光器。在 In P基质上用 Ga As SbAl As Sb布拉格反射镜达到高反射率。还测得低到 7m A的阈值电流 ,相应的阈值电流密度为 1.4 k A/cm2 。无电流注入时 ,腔共振精确集中 The University of California at Santa Barbara Group developed the first room-temperature, pumped, all-lattice matched, arsenide-stibium monolithic vertical-cavity laser operating at 1.55μm wavelength. High reflectivity is achieved with a Ga As SbAl As Sb Bragg Reflector on an In P substrate. The threshold current down to 7 mA was also measured with a corresponding threshold current density of 1.4 kA / cm2. When no current is injected, the cavity resonance is precisely concentrated
