Coherence, stability and localization resistance of extended two dimensional vertical cavity locked laser arrays

Summary form only given. Very large two dimensional (2D) vertical cavity phase-locked laser arrays were reported, exhibiting a single array mode operation for more than 500 laser elements, larger by an order of magnitude than what reported for one-dimensional (1D) arrays. Experiments were performed with laser arrays based on InGaAs-GaAs quantum well laser structure with epitaxially grown Bragg mirrors. Theoretical modeling was based on the rate equation approximation of the 2D coupled semiconductor laser array.
