We present the development of epitaxial regrowth processes to allow the realization of a PCSEL utilizing a quantum dot active region. An electron microscope-based study investigates the effect of group-III surface mobility on grating infill. An optimal process utilizing AlGaAs in-fill is used to fabricate QD devices that display room temperature ground state lasing at 1230 nm.
