Using Quantum Dots (QDs) as active region for a semiconductor laser can be preferable for various laser properties. However, the internal strain and the fabrication of an active region membrane can alter the structure properties and, consequently, the laser emission properties as well. In this contribution, we present the emission characteristics of a MECSEL based on InP QDs and emitting in the red spectral range. We discuss the influence of different membrane fabrication methods on the laser emission and the composition of the gain region.
