Liquid optical fibers with multistable core actuated by light radiation pressure

Résumé

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 on the excitation light beam. When the beam diameter is sufficiently small, we observe a well-defined stationary column diameter. In contrast, at larger beam diameter, the liquid column experiences complex spatio-temporal dynamics whose statistical analysis evidences an underlying multistable structure. Experimental observations are all supported by a full electromagnetic model that accounts for the wave guiding properties of the liquid column viewed as a step-index liquid- core/liquid-cladding optical fiber having an optically tunable core diameter.
