Abstract

A broadband amplified spontaneous emission (ASE) source of 88 nm is demonstrated using novel bismuth-based erbium-doped fiber (EDF) with the length of only 49.2 cm in a bi-direction pumping scheme. The maximum output power of 14.3 dBm is obtained under total pump power of 162 mW. The fiber loop mirror which works as a broadband reflector is responsible for the broadband output spectrum of this source according to the experiments.
