New Scientist;4/25/92, Vol. 134 Issue 1818, p17
Reports on a development in the United States where scientists have found a way to sculpt the end of an optical fiber into a precision lens which can gather 9 0 percent of a laser's light into the fiber. Size of the core of the fiber; How much is lost now; The process has been patented by AT&T.
