Ultra-strong squeezing of light demonstrated for ultrafast optical signal processing

A train carrying cargo has finite space. The amount of cargo that can be carried onboard is limited by the size of the cargo and the capacity of the train. Analogously, the amount of time taken up by an optical signal limits the amount of data that can be carried. Temporally shorter signals allow more data to be squeezed into a given time duration, in a method called optical time division multiplexing. Photonics researchers have recently succeeded in squeezing light in time by a factor of 11. Th...
