چکیده

In this paper, some optical characteristics of superluminescent light emitting diode (SLED) have been studied. The output power of SLED has been described by assuming a uniform carrier density distribution and zero reflection from the faces. In SLEDs, the the total optical power depends on the drive current and the output intensity, does not exhibit a sharp threshold. Typical values for SLED modules are for the optical bandwidth between 5 nm and 100 nm with central wavelengths covering the range between 400 nm and 1700 nm. The structure and the material composition used for the SLED chip affect the gain.
