Paper Abstract

The effect of gain spatial hole burning on antiguided arrays is analyzed for the first time. Nonresonant devices, due to the nonuniformity of the in-phase-mode intensity profile, experience self-focusing and multimode operation with increasing drive level similar to the behavior of evanescent-wave-coupled devices. Resonant and near-resonant devices (i.e. resonant-optical-waveguide (ROW) arrays), due to the uniformity of the in-phase mode, display some mild defocusing with increasing drive level, while the nearest high-order mode cannot reach threshold up to drive levels in excess of 10X threshold. These results explain the fundamental single-mode stability of ROW arrays, in excellent agreement with experimental data.
