A hybrid quantum well/quantum dot active region is used to obtain simultaneous three-state lasing at room temperature, via ground state and first excited state transitions of the quantum dots and the lowest energy transition of a single quantum well. The device exhibits a threshold current density of 1125 A/cm2 for achieving simultaneous three-state lasing over ∼160 nm.
