Active multi-mode interferometer (MMI) laser diodes were realized in InGaAsP/InP for high-power applications. They achieved increases in output powers of 90 mW, which correspond to 30% increases, as compared to the powers of regular single-lobe laser diodes fabricated simultaneously with the active MMI-LDs. The resulting maximum powers of the active MMI-LDs were 380 mW at a wavelength of 1.45 μm. The implemented active MMI-LDs showed stable regular single-transverse-mode outputs up to the maximum power.
