>> make it easier to phase lock multiple chips Another use for that is holography. If you can make a wafer-scale array of phase locked emitters overlayed with the ability to either attenuate or phase-shift each one, it becomes a nice (one color) holographic display. I'm assuming high divergence from each one.
