Abstract

Room temperature continuous wave operation of 2 µm photonic crystal surface emitting lasers (PCSELs) is reported. The GaSb-based PCSELs fabricated using highly uniform air-pocket retaining regrowth technology demonstrated threshold current densities of 500 A/cm2 and generated tens of mW of output power at 20 °C.
