Experiment of Distributed Optical Fiber Sensor Using Spatially-Selective Brillouin Scattering
TL;DR: In this paper, a distributed fiber sensor system based on spatially selective Brillouin scattering is demonstrated, using a single laser diode as a light source whose optical frequency is directly modulated by the injection current.

Measurement of Brillouin Gain Spectrum of Optical Fiber Using Direct Optical Frequency Modulation of Laser Diode
TL;DR: In this paper, a new method of measuring the Brillouin gain spectrum of optical fiber is proposed and demonstrated, where both the pump light and the counter-propagating probe light are generated from a single laser diode whose optical frequency is directly modulated by injection current modulation.
Simulation of Distributed Optical Fiber Sensors Using Spatially-Selective Brillouin Scattering
TL;DR: In this article, the authors implement numerical simulations for the distributed optical fiber sensor system that uses spatially selective Brillouin scattering, by treating the superposition of the optical-frequency-modulated pump/probe waves in the time domain.
Noise characteristics of a depolarized fiber-optic gyroscope incorporating single-mode fiber
TL;DR: A depolarized fiber-optic gyroscope that uses a length of singlemode fiber as a sensing loop fiber was constructed and characterized in this article, and an optimum phase modulation depth was found.
