Transition dynamics of spatially modulated Josephson junctions formed by optical soliton and surface plasmons


Güneş Aydındoğan, Koç University

This work investigates the crossing dynamics of photons between spatially coupled co-propagating soliton and surface-plasmon, which constitute a type of photonic Josephson junction. By introducing modulations to the spatial coupling, the crossing dynamics exhibit features similar as well as different to that of nonlinear Landau-Zener or Rosen-Zener type transitions. The dependence of the coupling to the soliton amplitude provides an inherent dynamic which may manifest distinct features in the transition characteristics. 

Bio: Güneş Aydındoğan started undergraduate study at Koç University in 2005. He received his B.Sc. degree in 2010 and continued to the M.Sc. programme, working under the supervision of Assoc. Prof. Kaan Güven. He received his M.Sc. degree in 2012 and continues his PhD with Prof. Güven. He is currently working on the nonlinear dynamical analysis of surface plasmon and optical soliton coupled systems. He is expected to graduate in January 2017.
