AlGaInAsSb-based multiple quantum well broad area lasers (BALs) with a monolithically integrated Fourier-optical 4f spatial-frequency-filter for transverse mode selection (TMS) are realized. Laser samples with filters for the selection of the fundamental transverse mode (no. 0; TMS0) and—for proof of principle-higher order modes, here exemplarily mode no. 8 (TMS8), are prepared; their emission characteristics are investigated. The concept of BAL and TMS integration within the active laser chip is verified.
