Temperature dependence of Yb-doped superfluorescent fiber source
Abstract
The influence of temperature on the output spectra and power of Yb-doped superfluorescent fiber source are investigated through a temperature-dependent model. The model is composed of steady-state rate equations and temperature-dependent cross section functions. Simulation results indicated that with temperature varying from 0 °C to 100 °C, the central wavelengths of the forward and backward output spectra shift from 1061.8 nm to 1070.8 nm and from 1045.8 nm to 1068.8 nm, respectively. Meanwhile, the total output power has a 15.3% reduction. These trends are further verified experimentally. This study offers a concise way of acquiring a superfluorescent fiber source with different central wavelengths.
