“A pair of studies from Penn Engineering provides new ways to increase information density in optical communications, paving the way for a massive increase in the bandwidth of fiber optic networks.

“With the enormous amount of data being generated around the world on a daily basis, traditional approaches for sending and receiving data becoming difficult to keep up. Because light is faster than electricity, scientists and engineers are now using photons of light instead of electricity to transmit data, and the demand for data centers that rely on fiber optic communication systems is rapidly increasing. 

“The challenge facing researchers is how to increase the amount of information that can be stored in light. It’s possible to layer data into different physical aspects of a light wave, such as its amplitude, wavelength, or polarization, but even these “multiplexing” strategies are reaching a bottleneck.

“Now, engineers are exploring some of light’s more difficult-to-control properties to increase the amount of data that can be stores in light waves. A matched pair of studies published in Science demonstrated one such system that can manipulate and detect a property of light known as its orbital angular momentum, or OAM, where light waves travel in a rotational, corkscrew pattern and allow information to be encoded within the direction and spacing of the wave’s rotation.

“A collaborative effort between researchers at Penn, Duke University, Northeastern University, the Polytechnic University of Milan, Hunan University, and the U.S. National Institute of Standards and Technology, this research is the first to be done on small semiconductor chips with enough precision that the system can be used for transmitting data…”

We provide this
article link to Penn Today, but do not try to make the whole article ours.  It does not belong to us. We only give you a flavour of it, so you can make up your own mind if you like and want to support the award-winning scientific research behind it, like we do.  Of course, we do not nor could support all the points made in any article we highlight, but that is part living in a democracy.  We believe the material is relevant to all and is necessary for their personal judgments.
