Breathing solitary-pulse pairs in a linearly coupled system [PDF]

open access: yes, 2014
It is shown that pairs of solitary pulses (SPs) in a linearly-coupled system with opposite group-velocity dispersions form robust breathing bound states. The system can be realized by temporal-modulation coupling of SPs with different carrier frequencies
