摘要

We use calculations and experiments to explore dual core optical fiber regardingits potential for robust transmission of coupled solitons at high data rate. The encouraging findings are that physical mechanisms can be identified that appear valuable to improved information transmission. Typical core separations, e.g., 14 to 40 microns, permit coupling and interaction of solitons, and also provide spatially distinct optical paths. Numerical simulations predict attractive, repulsive, and neutral combinations of effective forces between solitons on adjacent cores. The experiments show that substantial lengths, e.g., 20 meters, of dual core fiber will support not only, transmission of pulses approximating lowest order solitons, but mode locked laser oscillator operation as well. A remaining, and perhaps the single primary barrier, to practical realization of these states is the small (order of one part in 106), as yet unavoidable, difference in refractive index between adjacent cores in realizable multicore fiber. Potential solutions to the problems caused by small refractive index differences can be identified and further work is recommended.
