Abstract
We systematically measured the active‐area dependence of the threshold current density of GaInAsP/InP vertical‐cavity lasers at various temperatures. The threshold current density was found to increase monotonically with increasing active area, with the effect becoming more pronounced at higher temperature. This phenomenon is due to nonuniform current injection into the active region.Keywords
