Abstract

Summary form only given. We present here the first demonstration of a phase-locked array for which a DFB grating acts as an array-mode selector. Single-frequency and single-spatial mode operation are achieved to 0.45 W peak power. Thus, resonant antiguided optical waveguide (ROW) DFB laser diode arrays have potential for stable-beam, reliable operation to watt range coherent powers.
