Phased-array lasers with a uniform, stable supermode
Journal Article

· Appl. Phys. Lett.; (United States)
A phased-array semiconductor laser with identical coupled waveguides is designed to favor a uniform, stable supermode. All but the two outermost waveguides are equally spaced with the placement of the first and Nth guides chosen so as to increase their coupling coefficient by ..sqrt..2. The lowest and highest order supermodes have a uniform near-field intensity envelope and utilize the injected charges more efficiently. Whichever of these is favored at threshold should remain stable with increasing pumping or under modulation.
