Here, we simulate an amplifier based on an Yb-doped fiber. The numerical and graphical outputs are displayed with an html file.
| Fiber length: | 2 m |
| Fiber type: | Yb-germanosilicate |
| pump | signal | |
| Wavelength: | 940 nm | 1040 nm |
| Mode radius: | 3.8 µm | 4 µm |
| Input power: | 500 mW | 1 mW |
| Losses: | 0 dB/m | 0 dB/m |
| pump | signal | forward ASE | backward ASE | |
| Output power: | 9.49 mW | 222 mW | 1.59 mW | 120 mW |
| Gain: | -17.2 dB | 23.5 dB |
Fig. 1: Here, we show how the optical powers at various wavelengths vary within the fiber.
Fig. 2: This shows the spectrum of forward and backward ASE with a logarithmic (dB) vertical scale.
Fig. 3: The outputs are plotted as functions of the pump power.
Fig. 4: The outputs are plotted as functions of the signal input power.
