When an OEwaves customer referred to our lasers as having “Ridiculously Narrow Linewidth”, we took that as an expression of their amazement at how a semiconductor laser in a small, cellphone sized pac
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
