Paper Abstract

In this paper we present the idea and test results of an all-fiber unbalanced Mach-Zehnder interferometer for fiber Bragg grating shift demodulation. The interferometer design allows to monitor Bragg wavelength changes (caused by temperature or strain variations) as changes of intensity on the output detector. Furthermore the construction is cost-effective and based on simple optoelectronic components, which makes the solution attractive for application as a low cost fiber Bragg grating interrogator.
