Light-bending tech shrinks kilometers-long radiation system to millimeter scale

Phys.org   October 26, 2018 A team of researchers in the US (University of Michigan, Purdue University) used a laser to produce a pulse of visible light that lasts for one trillionth of a second. The array of antennae causes the light pulse to accelerate along a curved trajectory inside the crystal. The light pulse displaced electrons from their equilibrium positions to create dipole moments which accelerated along the curved trajectory of the light pulse resulting in the emission of synchrotron radiation much more efficiently at the terahertz range. The work demonstrates that synchrotron radiation could eventually help develop on-chip terahertz […]
