Nonlinear Physics Center, Research School of Physics and Engineering, The Australian National University, Canberra ACT 0200, Australia
Opt Lett 35:1692-4. 2010
..We also observe a large-angle total internal reflection of the soliton beam from an interface between liquid crystal and air...
Multimode nematicon waveguidesYana V Izdebskaya
Nonlinear Physics Center, Research School of Physics and Engineering, The Australian National University, Canberra, Australian Capital Territory 0200, Australia
Opt Lett 36:184-6. 2011
..We find that the nematicon waveguides operate in a bounded power region specific to each guided mode. Below this region, the guided beams diffract; above this region, the mode mixing and coupling give rise to an unstable output...
Observation of vector solitons with hidden vorticityYana V Izdebskaya
Nonlinear Physics Centre, Research School of Physics and Engineering, The Australian National University, Canberra ACT 0200, Australia
Opt Lett 37:767-9. 2012
..We employ nematic liquid crystal to generate stable vector solitons with counterrotating vortices and hidden vorticity. In contrast, the solitons with explicit vorticity and corotating vortex components show azimuthal splitting...
Counterpropagating nematicons in bias-free liquid crystalsYana V Izdebskaya
Nonlinear Physics Center, Research School of Physics and Engineering, The Australian National University, Canberra ACT 0200, Australia
Opt Express 18:3258-63. 2010
..We observe the dynamic instability of two counterpropagating nematicons in the form of time-dependent splitting and spatial entanglement...
Selective trapping of multiple particles by volume speckle fieldVladlen G Shvedov
Laser Physics Center, Research School of Physics and Engineering, The Australian National University, Canberra ACT 0200, Australia
Opt Express 18:3137-42. 2010
..The size distribution of trapped particles exhibits a narrow peak near the average size of an optical speckle. Thus, the speckleformed traps act as a sieve with the holes selecting particles of a similar size...

Dipole azimuthons and vortex charge flipping in nematic liquid crystalsYana V Izdebskaya
Nonlinear Physics Center, Research School of Physics and Engineering, The Australian National University, Canberra ACT 0200, Australia
Opt Express 19:21457-66. 2011
..The latter topological reactions involve triplets of vortex lines and resemble pitchfork bifurcations...
Generation of optical bottle beams by incoherent white-light vorticesVladlen G Shvedov
Nonlinear Physics Center and Laser Physics Center, Research School of Physical Sciences and Engineering, Australian National University, Canberra ACT 0200, Australia
Opt Express 16:20902-7. 2008
..We generate experimentally optical bottle beams from incoherent double-charge white-light vortices, and show that their parameters can be efficiently controlled by varying the beam focusing conditions...
