Abstract
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 conventional single-mode optical fibers. In
this paper we demonstrate experimentally 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.
In our experiments, we show the delaying of 2.7 ns pulses over slightly
more than one pulse length with only some residual broadening (<25%) of
the pulse width. We see no limit to extend this technique to the delaying of
GHz-bandwidth signals
