摘要：
We report the amplification characteristics at around 1.5 μm of a 0.9 m-long, 1000 ppm erbium(Er3+)-doped singlemode fluoride fiber. By using 1.48 μm laser diodes with 55 mW launched output as a pump source, a gain of 17.5 dB was obtained at 1.530 μm. A broad bandwidth of 40 nm was obtained, which may be suitable for WDM system use. © 1990 IEEE
