This article reports a modelling and experimental work on all-optical clock extraction for high bit-rate systems using self-pulsation mechanisms in semiconductor lasers at 1300 nm. External cavity DFB semiconductor lasers have been used, of both bulk and multiple quantum-well (MQW) types. ; Este artigo descreve um trabalho de modelização e realização pr...
This article describes two techniques for operating a semiconductor laser in a pulsed regime, namely the mode locking and injection locking mechanisms. For each one we present the operational principle, the theory and simulation results. We also describe the self Q-switching mechanism in multi-sections DFB lasers. ; Este artigo descreve duas técnicas de operar um laser de s...
