Researchers have demonstrated a method for "temporal
cloaking" of optical communications, representing a potential tool to
thwart would-be eavesdroppers and improve security for telecommunications.
"More work has to be done before this approach finds
practical application, but it does use technology that could integrate smoothly
into the existing telecommunications infrastructure," said Purdue
University graduate student Joseph Lukens, working with Andrew Weiner, the
Scifres Family Distinguished Professor of Electrical and Computer Engineering.
