Scientists created a real-life time cloak by using modulators to make the holes in time by bending light. Currently, practical applications include sending secret messages via fiber optic cables. It “can hide a continuous stream of events at telecommunications data rates – much quicker than a similar invention unveiled last year.” Continue reading for more information.
Here we demonstrate another technique for temporal cloaking which operates at telecommunication data rates and by exploiting temporal self-imaging through the Talbot effect hides optical data from a receiver. We succeed in cloaking 46 per cent of the entire time axis and conceal pseudorandom digital data at a rate of 12.7 gigabits per second.
This potential to cloak real-world messages introduces temporal cloaking into the sphere of practical application with immediate ramifications in secure communications.
