ABSTRACT:
A controllable semiconductor laser system including a plurality of semiconductor regions operated at unequal saturation photon densities to permit optical and/or electrical control of lasing in at least one resonant cavity formed therebetween. A pair of such regions may operate as a controllable laser at greater than 100% differential quantum efficiency.
