The linewidth of the laser does not change…in theory at least. In high performance lasers, such as OEwaves’ OE4030, the linewidth is stabilized by self-injection locking to a microresonator, so to cha
Lasers come in all sizes and performance grades. But the choice of the laser determines the ultimate system performance. Consider, for example, the use of a semiconductor laser in optical communicati
Developers, manufacturers, and users of lasers often need to characterize the noise performance of their device. Depending on the application, however, the parameter of interest could be phase noise,
