Numerical modeling of the formation of dynamically configurable L2 lens in a microchannel

Gupta A., Kitting J., Karampelas I.H., Flow Science Inc., US

The aim of this presentation is to describe the numerical modeling of a dynamically reconfigurable liquid-core liquid-cladding (L2) lens in a microfluidic channel, followed by a quantitative validation against the experimental results [1]. The lens [...]

Inkjet Printing of High Index Zirconia Nanocomposite Materials

Healy M.D., Guschl P., Wang X., Weinstein M., Pixelligent Technologies LLC, US

Abstract High refractive index (RI) nanocomposites have properties which surpass traditional polymers while maintaining manufacturability. Nanocrystal-polymer nanocomposites, when inkjet-printed, are useful to many display components and aid the development of next generation displays. This paper [...]

An Integrated Optofluidic System for Two-Dimensional Focus Point Control

Chao K.-S., Lin M.-S., Yang R-J, National Cheng Kung University, TW

Recently, optical methods have been widely used for biological and chemical detection in microﬂuidic or lab-on-a-chip systems. Precise adjustment of the optical path among multiple integrated components, such as flow cytometers, optical tweezers, and molecule [...]

Surface Plasmon Grating Coupled Emission from Organic Emitter for Detecting Refractive Index Variation

Chiu N.-F., Lee J-H., Lin C-W, National Taiwan Normal University, TW

We demonstrated the surface plasmon grating coupled emission (SPGCE) from photo-excited organic layer covered with metal thin film on the corrugated substrate. Directional emissions corresponded to the resonant condition of surface plasmon modes on the [...]

Re-dispersible ZrO2 powders for transparent high RI nanocomposite

Wang S-H., Sun Y.S., Chiang A.S.T., National Central University, TW

Previous products of nano-ZrO2 usually come in the form of dispersed sol. When they are to be used in organic/inorganic composite, the solvent accompanied may not be compatible with the target polymer system. We have [...]

Total flexibility in thin film design using polymer nanocomposites

Druffel T., Buazza O., Lattis M., Farmer S., Optical Dynamics, US

Optically clear, mechanically flexible nanocomposites are created by doping host polymers with nanoparticles having higher or lower refractive indices. The composite materials preserve the viscoelastic properties of the binding polymers and exhibit infinite tunability between [...]
