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...
As cities expand and become more complex, choices made over land use become increasingly relevant. Urban Green Spaces (UGS) are essential elements in the constantly evolving urban realm, as they can significantly contribute to the quality of life of the population. Green infrastructure planning is a complex process that should consider all dimensions of sustainable development. The investigation of public perc...
