| Abstract |
| cobalt ion-doped fiber is proposed and analyzed. A three-level system is employed
to model the amplified spontaneous emission (ASE) of the doped fiber pumped at
550 nm, and the rate and power propagation equations are solved to analyze the
effect of fiber length, active ion concentration, pump power and temperature on
the ASE. It is shown that the fiber has an ultra-broadband ASE in 1100-1900 nm
range, which will be promising for fiber communication system, fiber sensor and
medical imaging.
