In-phase coupled single-mode gain waveguide array laser.
We utilize a sliced slab waveguide structure to produce a gain waveguide array. With this array, an in-phase locked single-mode frequency output with a single-peak intensity distribution without sidelobes and a highly spatially suppressed far-field distribution has been obtained.
