Abstract
Two or more laser diodes are combined by crossing their cavities, and the multiple lasers share a common outcoupling aperture. By controlling the quantum wells in the active region, crosstalk between the devices can be eliminated. The multiple devices can also be made to crosstalk, and can be made coherent with respect to one another by mixing enough photons to phase lock the devices.
