Abstract

The spectral region between 1600 and 1800 nm is still a band where optical amplifiers struggle to achieve satisfactory gain and output power levels. The output power typically does not exceed few tens of milliwatts, what severely limits some applications. In this paper, the bismuth-doped fiber amplifier (BDFA) operating beyond 1600 nm is presented. We demonstrate the in-house developed BDFA capable of providing output powers that exceed 200 mW for wavelengths near 1700 nm. The performance of the amplifier is discussed and various properties of the device are presented such as gain characteristics and noise figure.
