Abstract

A zigzag array structure is proposed for passive coherent beam combining. Modal analysis was conducted via a transfer matrix method to demonstrate the support of a single supermode in this structure with a large modal discrimination. The performance of the proposed structure against the phase variation is also investigated by calculating the modal loss with different strengths of phase variation. The scalability of this structure is estimated from the perspective of brightness in two situations: the fully correlated one and the adjacent-correlated one. A brightness saturation behavior is observed for the latter with a sufficiency of available emitters in an array.
