Brillouin distributed sensing using localized and stationary dynamic gratings

Luc Thévenaz, Nikolay Primerov

In this work, we apply a recent technique for the generation of stimulated Brillouin scattering (SBS) dynamic gratings that are both localized and stationary to realize high-resolution distributed temperature sensing. The gratings generation method relies ...

Distributed sensing employing stimulated Brillouin scattering in optical fibers

Luc Thévenaz

Disclosed are methods and devices for distributed sensing of a measurable parameter employing stimulated Brillouin scattering in an optical fiber. A frequency-modulated or phase-modulated light wave is transmitted into the optical fiber. A scattered light ...

Brillouin optical time-domain analysis over a 240 km-long fiber loop with no repeater

Luc Thévenaz, Sang Hoon Chin, Marcelo Alfonso Soto Hernandez

In this paper we combine the use of optical pulse coding and seeded second-order Raman amplification to extend the sensing distance of Brillouin optical time-domain analysis (BOTDA) sensors. Using 255-bit Simplex coding, the power levels of the Raman pumps ...

High-resolution Brillouin fiber sensing using random phase coding of the pump and probe waves

Luc Thévenaz, Nikolay Primerov

Distributed temperature measurements with 1.2 cm resolution based on stimulated Brillouin scattering (SBS) in standard fibers are reported. High resolution is achieved by phase-coding both pump and probe waves with a high-rate, pseudo-random binary phase c ...

Society of Photo-Optical Instrumentation Engineers (SPIE)2012

In this Letter, we combine the use of optical preamplification at the receiver and optical pulse coding techniques with an optimized modulation format to effectively extend the sensing range of Brillouin optical time-domain anal ysis (BOTDA) sensors. Combi ...

Raman-based distributed temperature sensor with 1 m spatial resolution over 26 km SMF using low-repetition-rate cyclic pulse coding

Marcelo Alfonso Soto Hernandez

We experimentally investigate the benefits of a new optical pulse coding technique for long-range, meter and submeter scale Raman-based distributed temperature sensing on standard single-mode optical fibers. The proposed scheme combines a low-repetition-ra ...

2011

In this paper we demonstrate a long-range distributed strain and temperature optical fiber sensor using Brillouin optical time-domain analysis in conjunction with optical pulse coding. Compared to standard BOTDA, pulse coding provides higher signal-to-nois ...

10 gbps VCSELs with high single mode output in 1310nm and 1550 nm wavelength bands

Elyahou Kapon, Alexandru Mereuta, Vladimir Iakovlev, Andrei Caliman

A new generation of 10 Gb/s wafer fused VCSELS show high single mode output in excess of 2mW at 80 degrees C (6mW at 20 degrees C) in the 1310 nm band and 1.5mW at 80 degrees C (4 mW at 20 degrees C) in the 1550 nm band. Error free transmission over 10 km ...
