We demonstrate expeimentally a novel approach for fast light generation based on a wideband compound spectral resonance using stimulated Brillouin scattering. The pulses experience fast light with extremely reduced distortion and small amplitude change. ...
In this paper, we study a coherent optical MIMO (COMIEMO) multi-mode fiber link proposed for enhancing the fiber information capacity. We examine the statistical characterization of the equivalent MIMO channel and the improvement in the fiber capacity due ...
A method for seepage and settlement monitoring in earth embankment dams using fully distributed sensing along optical fibres is proposed. A model is developed for simulating and monitoring seepage and settlement systems. This model relates the strains and ...
We experimentally demonstrate that Brillouin slow light with an arbitrary large bandwidth can be readily obtained in conventional optical fibers using a simple and inexpensive pump spectral broadening technique ...
Slow and fast light with null amplification or loss of a light signal is experimentally demonstrated. This novel method for producing zero-gain slow and fast light takes advantage of the great flexibility of stimulated Brillouin scattering in optical fiber ...
Brillouin slow light in optical fibers is a promising technique for the development of all-optical buffers to be used in optical routers. The main drawback of this technique up to now has been its narrow bandwidth, normally restricted to 35 MHz in conventi ...
A method to achieve an extremely wide and flexible control of the group velocity in an optical fiber using stimulated Brillouin scattering is presented. Group velocities below 71,000 km/s on one hand, well exceeding the speed of light in vacuum on the othe ...
Instruments for distributed fiber-optic measurement of temperature are now available with temperature resolution of 0.01°C and spatial resolution of 1 m with temporal resolution of fractions of a minute along standard fiber-optic cables used for communicat ...
We propose a novel method to realize self-induced fast light and signal advancement with no distinct pump source in optical fibers, based on stimulated Brillouin scattering. This scheme will be helpful for real application systems. ...
In a previous paper (Song et al., 2005) we reported the first experimental demonstration of pulse advancement with gain in optical fibers using stimulated Brillouin scattering (SBS). We tested the two methods described above to achieve gain-assisted fast l ...
