Strong enhancement of interaction of optical pulses induced by oscillatory instability

Short optical pulses have numerous applications including high bit rate communications, optical tomography, spectroscopic measurements, material processing, frequency standards, etc. In relation to applications of temporal and spatial localized structures of light for all-optical information transmission, storage, and processing, the problem of interaction those structures is of particular importance. On one hand, interaction of optical pulses implies strict limitations on the amount of information that can be transmitted using a sequence of closely packed pulses. On the other hand, different bound states of localized structures of light arising as a result of their interaction could serve as an “alphabet” useful for increasing the amount of encoded information.
