Paper Abstract

Based on analytical continuation of the round-trip condition, in contrast to existing rate equations. Threshold current density, slope efficiency, and threshold gain of cascade VCSEL as a function of number of active regions for the different size-dependent paramenters such as the cavity of length and thickness of each active region are discussed as applications. The results showed behavior of an almost linear increase in slope efficiency and a reduction in threshold current density with the number of stages.
