Abstract : We studied soliton based gigabit networks with an emphasis Air Force interests. We sought parallel data streams with a precise temporal relationship between envelopes and carrier phases of the pulses. We examined nonlinear interactions that stabilize the temporal relationship of pairs of pulses propagating on similar, but physically distinct optical paths. We constructed a simple local area network having 4 km of single mode dispersion shifted fiber operating at 1.33 microns and 1.36 6Hz. We explored dual core fiber. We found a practical barrier in the uncontrolled variations in the relative optical path delay in the two Cores. As a means of obtaining greater control over short optical pulse parallel data streams we explored an adjustable temporal delay caused by a compact periodic semiconductor structures. We reduced the group velocity of a 2 psec pulse to 1/18th the free space velocity in an adjustable manner in an 8 micron thick GaAs/A1GaAs structure. The losses were as little as 5% and negligible pulse distortion occurred. We also used numerical simulations to explore the dynamics of enhanced nonlinear optical pulse interactions in microresonators. The latter efforts are useful in addressing practical barriers encountered in this work.
