Reversible nonreciprocity in photonic structures infiltrated with liquid crystals (2009)
Miroshnichenko, Andrey E., Brasselet, Etienne, Kivshar, Yuri S.
We demonstrate how to achieve reversible nonreciprocal optical response in a periodic photonic structure with a pair of defects, one of them being a nonlinear liquid crystal defect layer. The twin...
Optical Vortices from Liquid Crystal Droplets (2009)
Brasselet, Etienne, Murazawa, Naoki, Misawa, Hiroaki, Juodkazis, Saulius
We report on the generation of mono- and polychromatic optical phase singularities from micron-sized birefringent droplets. This is done experimentally by using liquid crystal droplets whose three...
Laser microfluidics: fluid actuation by light (2009)
Delville, Jean-Pierre, Schroll, Robert D., Chraibi, Hamza, Issenmann, B., Wunenburger, Régis, ...
The development of microfluidic devices is still hindered by the lack of robust fundamental building blocks that constitute any fluidic system. An attractive approach is optical actuation because...

Liquid optical fibers with multistable core actuated by light radiation pressure (2008)
Brasselet, Etienne, Wunenburger, Regis, Delville, Jean-Pierre
We report on spatio-temporal behavior of self-adapted dielectric liquid columns generated and sustained by light radiation pressure. We show that single or multi-valued liquid column diameter depends...
Brasselet, Etienne, Delville, Jean-Pierre
We present an electromagnetic model describing liquid-core liquid-cladding optical fibers sustained by light radiation pressure that encompass the contribution of all the allowed propagating modes....
Bridging dielectric fluids by light: a ray optics approach (2008)
Schroll, Robert D., Brasselet, Etienne, Zhang, Wendy W., Delville, Jean-Pierre
Rayleigh-Plateau instability is known to impose a stability limit for the length of a liquid bridge in weightless conditions. This fundamental limit may be exceeded by using a light field to form and...

All-optical switching and multistability in photonic structures with liquid crystal defects (2007)
Miroshnichenko, Andrey E., Brasselet, Etienne, Kivshar, Yuri S.
We demonstrate that one-dimensional photonic crystals with pure nematic liquid-crystal defects can operate as all-optical switching devices based on optical orientational nonlinearities of liquid...
Light-driven liquid crystalline nonlinear oscillator under optical periodic forcing (2007)
Krimer, Dmitry O., Brasselet, Etienne
An all-optically driven strategy to govern a liquid crystalline collective molecular nonlinear oscillator is discussed. It does not require external feedbacks of any kind while the oscillator and a...
