TLDR
In this article, a direct current sensor based on all-fiber Mach-Zehnder interferometer is demonstrated, where the phases of interferometric lights are modulated by heat effect when current flowing through a thin metal tube.Abstract:
A direct current sensor based on all-fiber Mach-Zehnder interferometer is demonstrated in this paper. The phases of interferometric lights in the interferometer is modulated by heat effect when current flowing through a thin metal tube. The charactersistics of current sensing are studied experimentally. Adopting the wavelength scale method, in the case of elimination of environmental perturbation, the wavelength changing range is 32nm when the current changes from 0 to 1.8A. The shifting wavelength is linear to the power and the linear fitting is 0.9987. The tuning efficiency is approximately 19.47nm/W.read more

Experimental characterization of a dynamically gain-flattened erbium-doped fiber amplifier
TL;DR: In this article, an erbium doped fiber amplifier (EDFA) was designed and experimentally characterized, which possesses a wavelengthindependent gain spectrum, independent of the operating level of the gain (dynamic gain flatness), and without requiring any gain-level-dependent control of any parameters.
