            Abstract : 
Supermode structures of phase-locked diode laser arrays are predicted using the finite-element technique. In this approach, modal information such as effective refractive index, modal gain and near-field pattern can be obtained straightforwardly by solving a standard matrix eigenvalue problem. Application to an eight-element array successfully demonstrates the power of the method.
