100 mW High-Power Broadband Superluminescent Diode Using Selective Area Growth at 1.5-μm Wavelength

A superluminescent diode with selectively grown multi-quantum-well layer is realized with greater than 100 mW output power, a spectral bandwidth of 60 nm and spectral modulation of less than 0.3 dB at 1.5 mm wavelength.
