【Abstract】 The parameters such as the output optical power, spectra and extinction ratio of a Multi-Quantum Well Super-Luminescent Diode (MQW-SLD) module with about 1.55μm In-GaAsP/InP material were measured and analyzed entirely when it was operating with different current and at different temperatures, and the relation between these parameters and the operation current and temperature was investigated. The measurement results showed that the MQW-SLD had a soft threshold, and its output optical power, peak wavelength, 3dB bandwidth and extinction ratio varied with operation current and temperature.更多还原
