Dynamics of Multifrequency Oscillator Communities

“…Networks of coupled oscillators describe synchronization in lasers [1] and Josephson junctions [2], atomic recoil lasers [3], electrochemical oscillators [4], applauding persons in a large audience [5], pedestrians on footbridges [6] and many other systems. In the simplest setup, when all oscillators are of a same type and coupled via a mean field, the synchronization transition has been treated by Kuramoto [7,8] in analogy with the mean field theory of ferromagnetic phase transitions.…”

Reconfigurable semiconductor laser networks based on diffractive coupling

“…One of the most commonly attempted techniques for the implementation of global coupling within an array of lasers employs Talbot self-imaging [7]. Until today, however, no successful creation of large, scalable, and reconfigurable laser network has been demonstrated.…”

Optically coupled lasers

“…In the case of the uniform filling the composite aperture by radiation, the side maxima of the far-field intensity distribution are efficiently suppressed when the transverse size of the array element U is equal to the array period d. Fig.3 [5] shows the calculated dependences of the fraction yc of the power contained in the main maximum on uld and ofthe maximum fraction yemax of power on N for 1D array with the initial in-phase field distribution. 'The wave-front correction in the doubling plane (at the quarter Talbot distance from the array) was achieved by x12 phase modulation with the d period.…”
