The first oxide-confined GaSb-based vertical-cavity surface emitting laser operating in the mid-infrared is demonstrated. Laser operation at -20°C in continuous wave is achieved with a device emitting around 2.3 µm. The influence of the lateral confinement on laser performances is presented and discussed.
