Complete All-Optical Silica Fiber Isolator via Stimulated Brillouin Scattering
Brillouin scattering electrostriction optical fi bers optical isolators.
2011/8/10
This study demonstrates the theoretical operation of an all-optical silica fiber isolator using stimulated Brillouin scattering. Two pump sources that copropagate through a double-mode fib...
Distributed Birefringence Measurement of Polarization Maintaining Fiber Using Transient Brillouin Grating
Fibers polarization maintaining Scattering stimulated Brillouin
2010/6/10
We propose a true distributed birefringence measurement of polarization-maintaining fiber based on transient Brillouin grating. A birefringence variation of 2.5×10 -6 along 8 m Bow-tie fiber is measur...
Stimulated Brillouin Scattering based In-Band OSNR Monitoring for 40G and 100G Deployment in Optical Networks with 100 GHz and 50 GHz Channel Spacing
Fiber optics communications Fiber optics links subsystems
2010/6/10
We present an improved approach for SBS based in-band OSNR monitoring with a drastic enhancement of the dynamic monitoring range for 44.6 Gbps DPSK and 112 Gbps DP-QPSK signals by intentionally adding...
Optical Pulse Coding Applied to Distributed Temperature Sensor Using Coherent Detection of Spontaneous Brillouin Frequency Shift
Optical Pulse Coding Applied Distributed Temperature Sensor Spontaneous Brillouin Frequency Shift
2008/8/3
A 53-km Simplex-coded distributed temperature sensor based on coherent detection of Brillouin frequency shift is demonstrated with 1.1 K and 35 m resolutions, using only 10 mW input peak power.
