Experimental Results of the Superluminescent Fiber Laser Sources for Fiber Optic Sensors

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.
