Abstract
Nowadays, there is a growing need for light-sources meeting seemingly contradictory requirements such as very narrow emission spectrum and high optical power or high quality of the light beam combined with a broad emission spectrum. These specific requirements trigger the development of optoelectrical elements such as superluminescent diodes (SLD) and semiconductor optical amplifiers (SOA). In this presentation, we will review the basic work principles of SLDs and SOAs as well as discuss the important challenges such as: suppression of the feedback from the device facets, reduction of gain saturation, broadening of SLD emission spectra. We will also analyze the limits related to self-heating.
