Coupling of parallel-cavity laser arrays with high-contrast-reflectivity mirrors

Research output: Contribution to journalArticlepeer-review


A coupled-mode formulation is presented for parallel cavities of a laser array. The interaction between neighboring elements is via diffraction resulting from perturbation of the boundary conditions. Each highreflectivity cavity mirror is surrounded by a much-lower-reflectivity background, which, for practical purposes, is considered to be zero. The formulation applies both to ordinary laser arrays and to vertical-cavity laser arrays with high-contrast laterally patterned mirrors. Some examples are considered and compared against exact numerical calculations.
