Abstract

The Pr3+-doped fiber amplifier (PDFA) is a candidate for use as an optical amplifier in 1.3 µm transmission systems(1). A recent paper reporting that a signal gain of 28.3 dB was obtained by laser diode pumping strongly suggests that the PDFA is a device with the potential to be applied in 1.3 pm optical systems(2).
