A new scheme for building two dimensional laser arrays that operate in the single supermode regime is proposed. This is done by introducing an optical coupling between the laser array and lossy pseudo-isospectral chains of photonic resonators. The spectrum of this discrete reservoir is tailored to suppress all the supermodes of the main array except the fundamental one. This spectral engineering is facilitated by employing the Householder transformation in conjunction with discrete supersymmetry. The proposed scheme is general and can in principle be used in different platforms such as VCSEL arrays and photonic crystal laser arrays.
提出了一种构建在单超模模式下工作的二维激光阵列的新方案。该方案通过在激光阵列和损耗型准等谱光子谐振器链之间引入光学耦合来实现。这个离散储层的光谱被精心设计，以抑制主阵列的所有超模，除了基本超模。这种光谱工程通过使用 Householder 变换和离散超对称性来实现。所提出的方案是通用的，原则上可以用于不同的平台，如 VCSEL 阵列和光子晶体激光阵列。
