Abstract: The laser emission spectra, far-field patterns, and near-field emission intensity distributions of InGaAs/GaAs/AlGaAs edge-emitting quantum well laser diodes with ultra-broad optical waveguide were studied as functions of the pump current and temperature. It was shown that lasing in the ground state occurs in the second-order mode and in the excited state in the fundamental mode.
