Development of superluminescent diodes and optical amplifiers

For certain, growing, class of applications it is necessary to have better suiting combination of beam and spectral quality. This specific combination of beam quality and spectrally broad emission can be delivered by superluminescent diodes (SLEDs). Additionally, the expected advent of nitride integrated photonic circuits and visible light communication call for new active optical elements, such as optical semiconductor amplifiers (SOA). Within this work we will present the progress in the development of broad spectral emission (>15 nm and OSA amplifiers which reach the gain of 10-20 dB at violet-blue wavelength range.
