Novel high-power superluminescent diodes with wide active channels

Two types of superluminescent diodes (SLDs) based on DQW (InGa)As/(GaAl)As/GaAs nanostructures with 25 μm-width multimode active channels emitting at 890 nm and 950nm were studied. They ensure CW optical power of more than 100 mW ex standard 50 μm multimode fiber (MMF).
