摘要：It is shown that minimum delay distortion is realized in a graded-index multimode optical fiber comprising an inner core of radius a surrounded by a suitable cladding when the refractive index n(r), at any radius r less than a, is given by n(r) = no [1 -2 DELTA (r/a)2<->2 ] 1/2, WHERE NO IS THE REFRACTIVE INDEX AT THE CENTER OF THE FIBER CORE, A IS THE CORE RADIUS, NC IS THE REFRACTIVE INDEX OF THE CORE AT R = A, AND DELTA = NO = NC/NO. A variety of suitable claddings are described.
