Abstract

Here we propose novel active multi-mode-interferometer (MMI) laser diodes (LDs) for 14XX nm fiber amplifier pump applications. The waveguide of the LDs is consisted from 1x1-MMI couplers integrated with 1^st order-mode permitted waveguides to enhance the total active area. Although there is no single-mode waveguide region inside the cavity, the novel active MMI-LDs emitted in stable singletransverse-mode output up to maximum output power. Moreover, they achieved high output power of 1.46 W, and low driving voltage of only 1.75 V at 1 W output power.
