摘要
A broad-area InGaAs submonolayer (SML) quantum-dot vertical-cavity surface-emitting laser (QD VCSEL) for fiber-optic applications is demonstrated. The active region of the device contains three InGaAs SML QD layers. Each of the InGaAs SML QD layers is formed by alternate depositions of InAs (<1 ML) and GaAs. A maximum CW output power of 12.2 mW at 30 mA has been achieved in the 990 nm range, with a threshold current of 1 mA.
