Optically-pumped circularly-polarized lasing in a (110)-oriented VCSEL based on InGaAs/GaAs QWs

We demonstrated circularly-polarized lasing in a (110)-oriented VCSEL based on InGaAs/GaAs QWs by optical pumping for the first time. High degree of circularly polarization (0.94) was achieved reflecting long spin relaxation times in (110) QWs.
