Abstract

The unique temperature dependent modal partitioning at threshold of dual resonator VCSELs is measured and modeled accounting for the spectral/spatial overlap of the longitudinal modes with both active regions. In summary, the temperature dependence of the threshold current of coupled microcavity lasers can be understood by accounting for both spatial and spectral overlap between the cavity resonances and gain bandwidth.
