Abstract :
The amplification characteristics at around 1.5 mu m of a 0.9-m-long, 1000-p.p.m Er/sup 3+/-doped single-mode fluoride fiber are discussed. By using 1.48- mu m laser diodes with 55-mW launched output as a pump source, a gain of 1.75 dB was obtained at 1.530 mu m. A broad bandwidth of 40 nm was obtained, which may be suitable for wavelength-division multiplexing (WDM) system use.<>
