High-power broad-band superluminescent diode with low spectral modulation at 1.5-mu m wavelength

A 1.5-mu m wavelength superluminescent light source operating at a heat sin k temperature of 13 degrees C with the following properties was realized: 2 0-mW continuous wave output power, 130-nm spectral bandwidth, and 0.2-dB sp ectral modulation. This light source consists of an angled facet single-mod e waveguide with a rear absorption region. These results were obtained by o ptimizing the epitaxial design, the waveguide design, and the device mounti ng.
