Abstract :
A model has been developed of the zero-order supermode stability with drive current for real index-guided laser arrays allowing for the effect of injected carriers on the active-layer dielectric constant. It is difficult to design simultaneously for a high output power capability and zero-order supermode stability over the full dynamic range of the array.
