Abstract

A 24dB gain bismuth-doped fiber amplifier at 1430nm pumped by a 65mW commercial laser diode at 1310nm is reported for the first time (to our knowledge). A 3dB bandwidth of about 40nm, a noise figure of 6dB, and a power conversion efficiency of about 60% are demonstrated. The temperature behavior of the gain spectrum is examined.
