Mark.JUK writes "Scientists' working at New York's Institute of Ultrafast Spectroscopy and Lasers (IUSL) have discovered a new way of mapping the multiple higher channels / more complex light in an optical fibre (i.e. fibre optic cable), which could allow telecommunications operators the ability to harness "untapped data channels" and thus improve broadband speeds and internet capacity across the world. Critically the new model allows scientists to follow polarization and other changes as light travels, which also gives you an insight into the material that it travels through.
Until recently it wasn't possible to map such light but all that has changed thanks to the globe-shaped Higher Order Poincare Sphere (HOPS) model. Professor Robert Alfano explains: "The sphere facilitates understanding, showing phase vortices are on poles and vector beams are on the equator. It organizes the relationship between these vortices of light. This kind of organization on the higher level Poincaré Sphere could clear the path to a number of novel physics and engineering efforts.""
