Paper Abstract

The fabrication and operating conditions for semiconductor laser arrays to be phase-locked are estimated in an analysis based on the van der Pol theory of the locking of coupled oscillators. Typical numbers for 10 pm spacing show tat the average aluminum concentration in adjacent stripes must be the same to within ≈10-4, the average epilayer thickness must be the same to within 0.2%, and there is a few percent tolerance on the stripe width and contact resistance. These close tolerances support the fact that high quality fabrication processing is usually required for phase-locked laser arrays, and increases in coupling may be desirable.
