Slow light has been extensively studied in coupled arrays of passive optical resonators, and several applications have been demonstrated. We developed a theoretical framework for the design and analysis of arrays consisting of active resonators, in particular vertical cavity surface emitting lasers (VCESLs), which have potential applications as a flexible photonic platform. Building upon this framework, several such applications were analyzed for both one- and two-dimensional coupled VCSEL arrays. In particular, the use of two-dimensional VCSEL arrays holds great potential for several interesting applications such as tunable optical waveguides or optical splitters.
