Zero-broadening measurement in Brillouin based slow-light delays.
A novel method for the achievement of zero-broadening in a SBS based slow-light system is discussed in theory and demonstrated experimentally. The system is realized just with a single broadened Brillouin gain. It is shown, that if the gain bandwidth is much broader than the initial pulse width, the output pulse width decreases with increasing pump power. A compression of approximately 90 % of ...
متن کاملZero-gain slow & fast light propagation in an optical fiber.
Slow & fast light with null amplification or loss of a light signal is experimentally demonstrated. This novel method for producing zero-gain slow & fast light takes advantage of the great flexibility of stimulated Brillouin scattering in optical fibers to generate synthesized gain spectra. Generation of optical delays and advancements with minor amplitude change is realized through the superpo...
متن کامل2. High Repetition Rate Pulse Source Using Pulse Compression through Optical Fiber
For next-generation optical networks, it is expected that transmission capacity will be increased by making high channel density and wide band WDM systems, and increasing data bitrate per wavelength channel. The high bitrate per channel system has great potential for cost reductions in comparison with wide broaden DWDM systems of the same transmission capacity, because of a fewer number of chan...
متن کاملWide-bandwidth, tunable, multiple-pulse-width optical delays using slow light in cesium vapor.
We demonstrate an all-optical delay line in hot cesium vapor that tunably delays 275 ps input pulses up to 6.8 ns and 740 input ps pulses up to 59 ns (group index of approximately 200) with little pulse distortion. The delay is made tunable with a fast reconfiguration time (hundreds of ns) by optically pumping out of the atomic ground states.
متن کاملAnalytical expression of pulse broadening in an arbitrary linear slow light medium.
We derive an analytical expression for the broadening of a Gaussian input pulse in an arbitrary linear slow light medium. The expression consists of two terms, one corresponding to amplitude broadening (low-pass filtering of the pulse bandwidth) and another corresponding to phase broadening (phase dispersion around the resonance). It is shown that for a Lorentzian gain profile, the amplitude br...
