In this paper, an innovative incoherent light source, based on the amplified spontaneous emission (ASE) phenomenon, is proposed. It is pumped at 980 nm and is based on a Tm:Er:Yb:Ho co-doped germanate glass fiber. The simulation predicts multi-wavelength emission peaks in a bandwidth of over 543 nm, in the wavelength range 1500-2100 nm. A numerical home-made solver, based on a nonlinear rate equations approach, has been ad hoc developed. The optimized ASE source is obtained by using a global optimization search based on a particle swarm optimization (PSO) algorithm, by varying the dopant concentrations, the fiber length and the input pump power. A total ASE output power as high as 50.71 mW is predicted for the optimized device.

Abstract
In this paper, an innovative incoherent light source, based on the amplified spontaneous emission (ASE) phenomenon, is proposed. It is pumped at 980 nm and is based on a Tm:Er:Yb:Ho co-doped germanate glass fiber. The simulation predicts multi-wavelength emission peaks in a bandwidth of over 543 nm, in the wavelength range 1500-2100 nm. A numerical home-made solver, based on a nonlinear rate equations approach, has been ad hoc developed. The optimized ASE source is obtained by using a global optimization search based on a particle swarm optimization (PSO) algorithm, by varying the dopant concentrations, the fiber length and the input pump power. A total ASE output power as high as 50.71 mW is predicted for the optimized device.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
