Distributed temperature sensing has been achieved by spatially resolved measurement of the probe time delay resulted from stimulated-Brillouin-scattering slow light. The temperature of a particular fi...
We report the first demonstration of a photonic chip based dynamically reconfigurable, widely tunable, narrow pass-band, high Q microwave photonic filter (MPF). We exploit stimulated Brillouin scatter...
We propose a scheme for on-chip isolation in chalcogenide(As2S3) rib waveguides, in which Stimulated Brillouin Scattering is used to induce non-reciprocal mode conversion within a multi-moded waveguid...
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...
Brillouin scattering is identified as a severe limitation in narrow line-width,bi-directional reflective systems. A spectrum management mitigation technique for triple-format OFDM signals is demonstra...
We demonstrate the first self-homodyne coherent detection of 10 Gbit/s PSK signals using Brillouin amplification of the optical carrier. Performance close to the ideal homodyne receiver is obtained by...
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...
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...
We demonstrate simultaneous monitoring of the optical signal to noise ratio (OSNR) for wavelength-division multiplexed 40 Gb/s signals using the back-reflected Stokes wave from Stimulated Brillouin Sc...
A high-power hybrid Brillouin/ytterbium fiber laser is demonstrated with an output power of 1 W. The laser operates in the single-frequency regime with an optical signal-to-noise ratio greater than 55...
Pulse coding techniques are proposed in combination with the use of Fabry-Perot lasers for simultaneous strain and temperature sensing based on hybrid spontaneous Raman-Brillouin scattering.Combinatio...
We demonstrate bit-rate tunable clock recovery of NRZ-DPSK signal. The signal is converted to RZ-OOK by demodulation and by phase erasure. Recovered clock signals from 4 to 13 GHz are obtained through...
Ge-doped laser fibers with suppressed SBS are proposed. By taking advantage of the difference between optical and acoustic properties, higher SBS thresholds of 3-5 dB are shown numerically while maint...
We propose a new optical fibre line testing system function for locating and identifying facilities in optical fibre networks with high accuracy by using 1 cm of multivalued Brillouin frequency shift ...
We present the first experimental verification of an almost distortion-free SBS based delay line. Since no distortion will be accumulated by the pulses, any delay can be achieved by a cascading of suc...
