1-Opto-capillary actuation of fluid interfaces

1.1 Opto-capillary interface deformation

Thermocapillary stresses are known to deform liquid interfaces. We investigate the case where heating is provided by a continuous Gaussian laser wave and showed that the direction of deformation of the liquid interface strongly depends on the viscosities and the thicknesses of the involved liquid layers. These results provide predictive behaviors for applications where localized thermocapillary stresses are used in confined situations, such as optofluidics.

1.2 Laser-microfluidics

The use of microfluidic drops as microreactors requires active control and manipulation. A route consists in heating locally two immiscible fluids to produce thermocapillary stresses along their interface. This opto-capillary coupling is implemented in adequate microchannel geometries to manipulate two-phase flows and propose a contactless optical toolbox including valves, droplet sorters and switches, droplet dividers or droplet mergers.

2-Optical and acoustic radiation pressure in bulk fluids and fluid interfaces

2.1 Optical radiation pressure at fluid interfaces

A. Ashkin demonstrated in the seventies that laser waves can deform fluid interfaces by momentum transfer. We have generalized this concept using binary liquid mixtures close to thermodynamic criticality to take advantage of the vanishing behavior of interfacial tension. We investigated this wave/interface interaction experimentally, theoretically and numerically. Moreover, the nonlinear wave/interface coupling leads to a large variety of interface shapes: bell, finger, needle, cone, or pacifier. Some of these shapes can in turn become unstable to give birth to liquid microjets or columns.

2.2 Optical radiation pressure in bulk liquids

Light momentum transfer can as well occur in bulk for the case of turbid liquids (suspensions, scattering fluids). In this case, the wave induces a liquid flow which can in turn deform fluid interfaces (if present) or keep continuous dripping from a needle tip. All optical microfluidic (channels and flows are here produced by light) becomes at hand.

2.3 Acoustic radiation pressure at fluid interfaces

Acoustic radiation pressure can as well deform fluid interfaces. As for the optical case, we investigated this wave/interface interaction experimentally, theoretically and numerically. Moreover, the nonlinear wave/interface coupling still leads to a large variety of interface shapes: bell, finger, needle, cone, or pacifier. Some of these shapes can in turn become unstable to give birth to liquid microjets or columns.

3-Photodeposition and patterning in liquids

3.1 Kinetics of liquid-solid phase transition induced by a resonant wave

Laser-induced phase transitions have been extended to the liquid-solid case using one-photon photochemical reactions. The late stage growth of photodeposits can be cast onto a universal behavior, whatever is the type of transition: photoexcitation, photodissociation or photocondensation.

3.2 Photo-patterning of flat and curved substrates

We applied photochemical deposition to surface patterning; at first on flat substrate with a particular emphasis for the dynamic control of photodeposited holographic gratings; and then to the hemisphere dissymmetrization of spherical particles, to produced Janus beads with a controlled coating, or surface patterned spheres.

4.1 Optical nonlinearity in critical liquid mixtures and suspensions

A. Ashkin demonstrated in the eighties that a 100 mw c.w. laser wave is able to induce large optical Kerr effect by manipulating the concentration of artificial liquid suspensions. We have generalized this concept using binary liquid mixtures close to thermodynamic criticality (micellar phases of microemulsions) to take advantage of the divergence of different properties and thus produce « infinite » Kerr response. Local (electrostriction) and nonlocal (thermodiffusion) effects were investigated using self-focusing and wave mixing experiments.

4.2 Laser-induced phase separation by optical manipulation

If the initial concentration is located close to a transition line, the variation of concentration produced by the laser wave (electrostriction and/or thermodiffusion) can be used to quench the mixture in composition and locally induce a phase separation. Drops are nucleated in the beam which behaves as an optical bottle.

Delville, C. Lalaude, E. Freysz, A. Ducasse, “Phase separation and droplet nucleation induced by an optical piston”, Phys. Rev. E49, 4145 (1994)

4.3 Optical Hysteresis

The drops nucleated by the optically induced phase separation behave as a set of ball lenses that self-focuses the exciting beam; the corresponding nonlinearity is not of optical origin but has instead a thermodynamic origin. Due to the S-shape of the Van der Waals isotherms, each drop behaves in fact as a bistable ball lens. As the field intercepting a drop depends on its modification by the previous lenses, the medium is equivalent to a set of self-induced bistable ball lenses coupled by the field. Consequently, by analogy with magnetization mechanisms, a hysteretical propagation is expected.

4.4 Early Stage Dynamics of liquid-liquid phase transitions in an optical bottle

To access to the nucleation and the early stage growth, the mixture has been quenched in a fring pattern (i) to avoid wetting, (ii) to make use of the tremendous sensitivity of wave mixing experiments and, (iii) to mean polydispersity effects over the droplet distribution.

4.5 Late Stage Dynamics of liquid-liquid phase transitions in an optical bottle

Beyond observations of classical droplet growth laws, the main originality of these investigations are linked to the confinement inside the optical bottle: (i) contrary to classical experiment no wetting coupling is expected, the beam behaves as a soft-wall bottle; (ii) buoyancy is balanced by radiation pressure, and (iii) the final droplet size is calibrated by the beam and thermodynamic properties. This offered the first opportunity to investigate droplet growth saturation up to thermodynamic equilibrium in the absence of wetting and hydrodynamic couplings.

5.1 Synthesis of nano and micro silica beads

In closed systems, control over the size of monodisperse metal-oxide colloids is generally limited to submicrometric dimensions. To overcome this difficulty, we explore the formation and growth of silica particles under constant monomer supply. Monodisperse spherical particles are produced up to a mesoscopic size and their growth can be described in an universal way.
