Abstract
Previously,
we proposed a data buffering system that makes use of a pair of white light
cavities. For application to telecommunication systems, it would be
convenient to realize such a device using fiber-optic resonators. In this
paper, we present the design of such a system, where the white light cavity
effect is produced by using stimulated Brillouin scattering. The system
consists of a pair of fiber-optic white light cavities placed in series. As
in the original proposal, the delay time can be controlled independently of
the bandwidth of the data pulses. Furthermore, we show how the bandwidth of
the system can be made as large as several times the Brillouin frequency
shift. We also show that the net delay achievable in such a buffer can be
significantly larger than what can be achieved using a
conventional recirculating loop buffer.
