Abstract
Data centers have become the major technology for collecting, storing,
and processing information. The latency requirement for transferring information
between servers has become more stringent from year to year as the speed of
the new generation of servers increases at an almost exponential pace. In
this paper, we propose a new method to compress switching information over
data sequence packets using temporal cloaking. The main advantages of this
method in comparison to electronic switching or the use of microelectromechanical
system technology are that the compression and removal of the switching information
are done entirely in the optical domain without increasing the packet duration
time, changing or adding overhead bits, reducing the signal-to-noise ratio,
or distorting the polarization or the phase of the signal. Only a small delay
is added to the signal due to the cloaking process. This method requires tight
synchronization; to address this issue, a mathematical model that describes
the effect of clock jitter on the system bit error rate performance is derived
in this paper. The same concept could also be used to increase the capacity
of legacy communication systems as well as in coherent digital communication
or analog communication, e.g., radio over fiber.
