Novel Er and Ce codoped fluoride fiber amplifier for low-noise and high-efficient operation with 980-nm pumping

We demonstrate the low-noise and high-gain operation of a fluoride Er/sup 3+/ and Ce/sup 3+/ codoped fiber (F-ECDF) amplifier with 980-nm pumping. A 980-nm-pumped F-ECDF with a length of only 45 cm exhibits a noise figure of 20 dB with a gain ripple of
