A Large Area Fiber Optic Gyroscope on multiplexed fiber network [PDF]
Optics Letters 38, p. 1092-1094, 2013, 2012 We describe a fiber optical gyroscope based on the Sagnac effect realized on a multiplexed telecom fiber network. Our loop encloses an area of 20 km^2 and coexists with Internet data traffic. This Sagnac interferometer achieves a sensitivity of about 1e-8 (rad/s)/sqrt(Hz), thus approaching ring laser gyroscopes without using narrow-linewidth laser nor ...

Distributed opto-mechanical analysis of liquids outside standard fibers coated with polyimide [PDF]
Applied Physics Letters - Photonics 4, 016105 (2019), 2019 The analysis of surrounding media has been a long-standing challenge of optical fiber sensors. Measurements are difficult due to the confinement of light to the inner core of standard fibers. Over the last two years, new sensor concepts have enabled the analysis of liquids outside the cladding boundary, where light does not reach.
