Researchers have developed a graded grating structure that can be scaled to dimensions compatible with light waves in both the terahertz and telecommunications portion of the spectrum. The achievement opens the door to the control of light waves on a chip. It has applications in spectroscopy, sensing and medical imaging, and it could hasten the arrival of all-optical telecommunication networks.
