Abstract

A vertical-cavity surface-emitting laser (VCSEL) based on (110) InGaAs/GaAs multiple quantum wells (MQWs) was fabricated and characterized. Circularly polarized lasing by optical pumping was demonstrated. A high degree of circular polarization, 0.94, was observed at 77 K, reflecting the long electron spin relaxation time in the (110) MQWs.

(110)基于量子阱的自旋VCSELs

制备了基于(110)InGaAs/GaAs多量子阱的垂直腔面发射激光器(VCSEL)，并对其进行了表征。证明了光泵浦的圆偏振激光。在77 K时观察到较高的圆极化度，为0.94，反映了(110)mqw中电子自旋弛豫时间较长。
