Open Access Open Access

Abstract

A 9.6 dB gain is observed at 1310 nm in a 5.0 cm bismuth-doped silica fiber. A launched pump power of 100 mW was obtained using an 810-nm laser diode. We demonstrated the simultaneous optical amplification at two wavelengths near second telecommunication windows, which is the range of zero-dispersion for silica fibers.
