50-Gbit/s, 3.8-kbit packets of optical return-to-zero data have been s
tored in a unidirectional fiber storage ring by use of a novel modulat
ion scheme in which the ratio of the fundamental modulation frequency
to the cavity fundamental frequency is rational (nonintegral). The mod
ulation technique should be applicable to lasers and to soliton transm
ission. (C) 1995 Optical Society of America
