Abstract :
This letter presents the experimental characterization of tapered and stripe superluminescent diodes fabricated from 980-nm high-power triple quantum-well InGaAs-AlGaAs semiconductor material. Record output powers in excess of 1.3 W pulsed have been measured, with 0.1-dB spectral modulation and maximum wall-plug efficiency 16%. Almost 1-W optical power into multimode optical fibers has been achieved with preliminary measurements of coupling efficiency.
