    • Dissipation Induced Modulation Instability: New Applications for Frequency Combs and Pulses Generation 

      Perego, A.M.; Turitsyn, S.K.; Staliunas, Kestutis (Institute of Electrical and Electronics Engineers (IEEE), 2018-11-15)
      Conference report
      Restricted access - publisher's policy
      We present a new technique based on a dissipation induced modulation instability, caused by unbalanced spectral dissipation for signal and idler waves, with applications in amplifiers and parametric oscillators but especially ...

    • Gain through losses in nonlinear optics 

      Perego, A.M.; Turitsyn, S.K.; Staliunas, Kestutis (2018-08-01)
      Article
      Open Access
      Instabilities of uniform states are ubiquitous processes occurring in a variety of spatially extended nonlinear systems. These instabilities are at the heart of symmetry breaking, condensate dynamics, self-organisation, ...

    • Linear and Nonlinear Bullets of the Bogoliubov-de Gennes Excitations 

      Kumar, Shubham; Perego, A.M.; Staliunas, Kestutis (2017-01-27)
      Article
      Open Access
      We report on the focalization of Bogoliubov–de Gennes excitations of the nonlinear Schrödinger equation in the defocusing regime (Gross-Pitaevskii equation for repulsive Bose-Einstein condensates) with a spatially modulated ...

    • Mode-locking via dissipative Faraday instability 

      Tarasov, N.; Perego, A.M.; Churkin, D.V.; Staliunas, Kestutis; Turitsyn, S.K. (2016-08-09)
      Article
      Open Access
      Emergence of coherent structures and patterns at the nonlinear stage of modulation instability of a uniform state is an inherent feature of many biological, physical and engineering systems. There are several well-studied ...

    • Pattern generation by dissipative parametric instability 

      Perego, A.M.; Tarasov, N.; Churkin, D.V.; Turitsyn, S.K.; Staliunas, Kestutis (2016-01-13)
      Article
      Open Access

    • Self-induced Faraday instability laser 

      Perego, A.M.; Smirnov, Sergey V.; Staliunas, Kestutis; Churkin, D.V.; Wabnitz, Stefan (American Institute of Physics (AIP), 2018-05-22)
      Article
      Open Access
      We predict the onset of self-induced parametric or Faraday instabilities in a laser, spontaneously caused by the presence of pump depletion, which leads to a periodic gain landscape for light propagating in the cavity. As ...
