Abstract

Bismuth-based EDF (Bi-EDF) is comprehensively studied as an alternative medium for optical amplification. The bismuth glass host provides the opportunity to be doped heavily with erbium ions to allow a compact high-power system design. The proposed methods have resulted in an increase of useable gain bandwidth and output power with minimal noise figure. The gain spectrum of the Bi-EDF amplifier has a measured amplification bandwidth of 80 nm with a quantum conversion efficiency of 20% obtained using 1480 nm pumping. This glass host will find more ample applications in the expansion of Dense Wavelength Division Multiplexing (DWDM) accommodating more channels in support of ever-increasing data traffic.
