Abstract We present a method that leverages projected light patterns as a mechanism for freeform deformation of a thin liquid film via the thermocapillary effect. We developed a closed-form solution for the inverse problem of the thin-film evolution equation, allowing us to obtain the projection pattern required in order to achieve a desired topography. We experimentally implement the method using a computer controlled light projector, which illuminates any desired pattern onto the bottom of a…

Exploiting cellular convection in a thick liquid layer to pattern a thin polymer film

A method to shape thin polymer films into periodic array of lenses is presented. A liquid layer placed on top of a much thinner polymer film is exposed to a transverse temperature gradient. The upper

Bidirectional Control of Flow in Thin Polymer Films by Photochemically Manipulating Surface Tension

The Marangoni effect causes liquids to flow toward localized regions of higher surface tension. In a thin film, such flow results in smooth thickness variations and may represent a practically useful

Voltage-programmable liquid optical interface

Recently, there has been intense interest in photonic devices based on microfluidics, including displays1,2 and refractive tunable microlenses and optical beamsteerers3,4,5 that work using the

Fluidic lenses with variable focal length

We demonstrate in this letter that variable focus lenses can be realized by pressure-induced deformation of a liquid interface. Large deflections can be achieved by exploiting the capillary pressure

The fast development in semiconductor technology is leading to very high chip power dissipation and greater non- uniformity of on-chip power dissipation with the result of localized hot spots, often

Patterning by Photochemically Directing the Marangoni Effect.

Polystyrene (PS) that has been exposed to ultraviolet light (UV) undergoes partial dehydrogenation of the alkane polymer backbone which increases its surface energy. Exploiting this photochemistry,

Two-dimensional self-assembly of colloids in thin liquid films

Steady thermocapillary flows of thin liquid layers. II. Experiment

The steady thermocapillary flow of nonvolatile layers, nonuniformly heated from below, is examined. The interactions among viscous forces, thermocapillarity, and hydrostatic effects give rise to the

Thermocapillary approaches to the deliberate patterning of polymers

The phenomenon of thermocapillarity, the response of fluids to thermal gradients due to thermal alteration of their surface tension, was first reported over a century ago. Since then, research has

Diffraction grating with suppressed zero order fabricated using dielectric forces.

TLDR
An electric-field-assisted method to produce diffractive optical devices is demonstrated and a fully cured solid phase grating was produced with the particular voltage-selected tailored optical property that the zero transmitted order was suppressed for laser light at 633 nm.
