An all-fiber scanning interferometer with a large optical path length difference
This paper describes the design of an all-fiber scanning interferometer. The main component of the system is a thermoelectric cooler that can rapidly heat or cool several meters of optical fiber. Over 4 cm variation…

High-resolution spectrally-resolved fiber optic sensor interrogation system based on a standard DWDM laser module
This paper presents a spectrally-resolved integration system suitable for the reading of Bragg grating, all-fiber Fabry-Perot, and similar spectrally-resolved fiber-optic sensors. This system is based on a standard telecommunication dense wavelength division multiplexing transmission module…

Rapid and broad wavelength sweeping of standard telecommunication distributed feedback laser diode
This Letter presents a method for the fast and broad wavelength sweeping of a standard setup of a diode’s active region and its immediate vicinity, which contain the diode’s optical feedback system. The selective and…
