ABSTRACT:
A self-focusing fiber array comprises three rows of self-focusing fibers, which are most closely packed and each of the self-focusing fibers substantially satisfies an equation of ##EQU1## where n.sub.o is the refractive index at the center of the cross section of each of the self-focusing fibers and n(r) is the refractive index at a distance r from the center of the cross section and a is a positive constant, and each of the self-focusing fibers is equal in the length under a condition of ##EQU2## and each end surface of the self-focusing fibers is in the same plane.
