“…This feature of the PLLA is very promising as it provides a basis for improvement of degradation characteristics of laser diodes. For example, in the most recent work PLLAs are already mentioned as an essential part of high-power laser diode design, regardless of whether or not the phase-locked lasing is achieved [2][3][4][5]. Obviously the nature of such near-field stabilization is closely related to the mechanisms of light confinement realized in PLLAs.…”

The nature of optical confinement in phase-locked laser arrays (PLLAs) with a mesa-stripe structure (MSS) has been studied. Two main mechanisms are distinguished, which are based on the variation of the waveguide effective refractive index due to MSS formation and on the refractive index modulation induced by the heating of the structure. Stable operation was achieved when either weak or strong optical coupling was realized in the PLLA. A phase-locked regime of radiation was obtained only for laser diodes with strong optical coupling. In the latter case the angle divergency was not greater than 2 • for the antisymmetric supermode emission from the PLLA.
