Experimental demonstration of valley-Hall topological photonic crystal at telecommunication wavelengths
Mikhail I. Shalaev, Wiktor Walasik, Alexander Tsukernik +2
Photonic topological insulators provide unprecedented possibilities to eliminate scattering losses and improve the efficiency of optical communication systems. Despite significant…
Orbital angular momentum beam instabilities in engineered nonlinear colloidal media
Jingbo Sun, Salih Z. Silahli, Wiktor Walasik +3
In this letter, we experimentally demonstrate the evolution of the optical vortex beams of different topological charges propagating in engineered nano-colloidal suspension of nega…
Reconfigurable Topological Photonic Crystal
Mikhail I. Shalaev, Sameerah Desnavi, Wiktor Walasik +1
Topological insulators are materials that conduct on the surface and insulate in their interior due to non-trivial topological order. The edge states on the interface between topol…
Trajectories and orbital angular momentum of necklace beams in nonlinear colloidal suspensions
Wiktor Walasik, Salih Z. Silahli, Natalia M. Litchinitser
Recently, we have predicted that the modulation instability of optical vortex solitons propagating in nonlinear colloidal suspensions with exponential saturable nonlinearity leads…
