Abstract

The processing technology of 1.3μm InAs-InGaAs quantum-dot VCSELs with fully doped DBRs grown by MBE will be demonstrated. The threshold currents of the fabricated devices with 10 μm oxide-confined aperture are 0.7mA, which correspond to 890A/cm2 threshold current density. And the threshold voltage of the device is 1.03V and maximum output power is 33 μW. The series resistance is 85 Ω which is 10 times lower then our preliminary work and 3 times lower then intracavity contacted InAs-InGaAs quantum-dot VCSEL. This relatively lower resistance can even comparable with the best result reported in InGaAs oxide-confined VCSELs with intracavity contact.
