A tunable liquid microlens includes an insulating layer, a droplet of a transparent conducting liquid disposed on a first surface of the insulating layer and a plurality of electrodes insulated from the droplet by the insulating layer. The plurality of electrodes are disposed such that they may be selectively biased to create a respective voltage potential between the droplet and each of the plurality of electrodes, whereby a contact angle between the droplet and the first surface is variable and the droplet may be repositioned along the first surface.

A tunable microlens uses a layer of photo-conducting material which results in a voltage differential between at least one of a plurality of electrodes and a droplet of conducting liquid when a light beam is incident upon the photo-conducting material. Such droplet, which forms the optics of the microlens, moves toward an electrode with higher voltage relative to other electrodes in the microlens. Thus, for example, when the light beam is misaligned with the microlens, the voltage differential causes the droplet, and hence the microlens, to realign itself with the beam.

Template-based methods fabricate organosilicate materials with mesoscopic structures. The methods include providing solutions of amphiphilic template molecules, mixing amphiphilic organosilicate precursors into the solutions to form mixtures, and evaporating solvent from the mixtures. The evaporation steps produce composites in which the amphiphilic organosilicate precursors have nontrivial mesoscopic structures.

A tunable microlens is disclosed that having a substrate with a non-zero radius of curvature in a way such that the microlens is able to achieve a new directional view without manual repositioning. The directional view of the microlens is altered by applying a voltage to at least one of a plurality of electrodes and thereby causing a voltage differential between the at least one of a plurality of electrodes and a conducting droplet of liquid disposed on the substrate with a non-zero radius of curvature. As the droplet moves to a different point along the surface of the substrate having a non-zero radius of curvature, the directional view the microlens changes in a way such that light originating from the new directional view is more advantageously focused into an image on a detector. The field of view of the microlens is limited only by the area on the substrate over which the droplet can move. An array of such microlenses may be used to facilitate a wider field of view.

A tunable optical lens includes a solid refractive optical lens, a channel adjacent to the solid refractive optical lens, and an extended body of liquid. A portion of the body forms at least part of an aperture stop for the lens. The portion of the body forms a meniscus that protrudes from or into the channel. The liquid is light-absorbing in the visual spectrum and/or in the near-infrared spectrum.

A process for forming a polymer template includes exposing a photoresist having polymer molecules to a light pattern and baking the photoresist to chemically react polymer molecules in portions of the photoresist that were exposed to light of the light pattern. The reacted polymer molecules have a different solubility in a solvent than chemically unreacted polymer molecules. The process also includes washing the baked photoresist with the solvent to produce a porous structure by selectively solvating one of the reacted polymer molecules and the unreacted polymer molecules. The porous structure can be used as template for forming porous structures of high refractive index materials.

An apparatus includes a planar substrate and an array of substantially transparent spherical micro-lenses forming a pattern. The pattern has an internal two-dimensional lattice symmetry on the planar substrate. Each micro-lens includes a convex bulge or a concave depression in a surface of the planar substrate. The micro-lenses and substrate include hydrogel that swells and contracts in a manner that is responsive to an environmental condition.
