Needle beam stays on point
A Harvard-led team of researchers has demonstrated a new type of light beam that propagates without spreading outward, remaining very narrow and controlled along an unprecedented distance. It could greatly reduce signal loss for on-chip optical systems and may eventually assist the development of a more powerful class of microprocessors.
