Experimental results of the superluminescent fiber laser sources for fiber optic sensors

Abstract

We are presenting experimental work on an erbium-doped fiber operating in the superluminescent regime. Experimental results for different pump power levels and fiber length show that the theoretical and numerical model could render useful information for predicting the total output power as a function of fiber doped length and the input pump power. These types of sources could have direct application in wavelength multiplexed arrangements of fiber sensors, fiber gyroscopes or, in general, in any sensors in which a broad wavelength and stable light source is required.

Rare-earth-doped fiber designs for superluminescent sources

“…In terms of quantum efficiency, for a given fiber length and a given pump power level, the total gain varies along the fiber depending on the absorption and emission Ga and Ge coefficients, which describe the absorption and emission parameters, respectively. 21 …”
