Abstract

Quantum-well and quantum-dot superluminescent diodes operating at 1.55 μm at high power have been developed. An optical output power of more than 600 mW in pulsed mode was produced from the device having 8 identical quantum-wells at room temperature, corresponding to the wall-plug efficiency of 28%. A continuous wave power was 26 mW (p-side up mounting) and the spectral modulation depth was 15% over the entire emission spectral width of 25 nm. For a device with 5 non-identical quantum-wells, a 255-nm spectral width centered at 1.55 μm was achieved. For a device with 5 closely identical layers of quantum-dots the gain medium exhibited a spectral width of 181 nm around 1.55 μm.
