Classification: CPC G  H | IPC G  H

Claim 18:
19. A method comprising:
using a photonic integrated circuit, splitting at least one input beam into multiple input beamlets and phase-shifting at least some of the input beamlets using phase modulators of the photonic integrated circuit;
using an array of optical amplifiers, amplifying the phase-shifted input beamlets and generating amplified beamlets;
diffracting at least some of the amplified beamlets by different amounts while the amplified beamlets are passing through at least one diffractive optical element;
combining the amplified beamlets after the diffracting to generate an output beam; and
controlling the phase modulators in order to adjust phasing of the phase-shifted input beamlets.
