Kevin Robinson

Researchers at Australian National University have created a high-power 980-nm diode laser specially designed to pump the erbium-doped fiber amplifiers crucial to high-bandwidth short-haul optical telecommunications networks. The laser's 50-µm-wide stripe boasts 1.8 W of peak power, which should be useful for pumping fiber amplifiers in wavelength division multiplexing (WDM) fiber optic networks. "WDM systems require higher pump powers to be able to amplify signals transmitted through the fiber systems simultaneously at different wavelengths," explained Chennupati Jagadish, head...Read full article
