    Optical analogues of complex phenomena: quantum systems, general relativity, chaos

    The equations describing the evolution dynamics of coupled few levels quantum system bear direct analogy with those describing several processes in classical wave optics, including the cases of evanescently coupled waveguides, polarization transformation optics, and nonlinear optical frequency conversion. This allows to exploit the same kind of robust approaches used in the quantum field in...

    The dynamics of nonlinear sum frequency generation is analogous to spin current dynamics in magnetic fields: the signal and idler complex amplitudes represent the two-dimensional spinor; the nonlinear coupling (governed by the undepleted pump and nonlinear modulation) represents the strength and direction of the magnetization; and the transverse Laplacian of the beams represent the kinetic...

    Optical computation is an emerging scheme in quantum transport, quantum simulation and machine learning. Computation exploiting light field can be performed in the time needed for a laser pulse wave-front to be shaped by a phase mask which can be as short as few femtoseconds: the calculation can performed at the “speed of light”.
    Spin glasses serve as prototype models, capable of providing...

    We analyze in details experimental measurements of chaos generated by a laser diode subjected to phase-conjugate feedback realized using a SPS photorefractive crystal in a CAT configuration. In addition to the typical figure of merit, ie, chaos bandwidth, the corresponding spectral flatness and permutation entropy at delay is analyzed. The experiments reveal that chaos, with a bandwidth up to...
