Understanding the magnitude and temporal structure of variations in solar ultraviolet and extreme ultraviolet irradiance is critical to understanding solar forcing of the Earth’s upper and middle atmosphere and hence to assessing the relative impac

The exploitation of high-speed, WDM, and coherent optical systems will require a laser transmitter which not only exhibits a high modulation bandwidth but is also of narrow linewidth and low chirp. The active OE element must also be manufacturable, h
