A Thermally Tunable Microlens Array on Indium Tin Oxide Glass
نویسندگان
چکیده
We present a polydimethylsiloxane (PDMS) microlens array on a glass substrate. By adjusting the temperature with indium tin oxide (ITO) microheaters, the properties of the individual microlenses are actively tuned without mechanical movement. We characterize the temperature-dependent changes of the microlenses by focal length and magnification measurements. Experimental results demonstrate that the thermally tunable microlenses can potentially be used for biological imaging and other applications.

Polymer-stabilized liquid crystal microlens array with large dynamic range and fast response time.
We report a polymer-stabilized liquid crystal (LC) microlens array with a large dynamic range and fast response time. The top substrate has a planar indium-tin oxide (ITO) electrode, while the bottom substrate has two patterned ITO electrodes for generating a fringing field and uniform longitudinal field. The fringing field is utilized to create the desired gradient refractive index profile in ...
متن کاملSoft holographic interference lithography microlens for enhanced organic light emitting diode light extraction.
Very uniform 2 μm-pitch square microlens arrays (μLAs), embossed on the blank glass side of an indium-tin-oxide (ITO)-coated 1.1 mm-thick glass, are used to enhance light extraction from organic light-emitting diodes (OLEDs) by ~100%, significantly higher than enhancements reported previously. The array design and size relative to the OLED pixel size appear to be responsible for this enhancemen...
متن کاملTunable two dimensional optical beam steering with reconfigurable indium tin oxide plasmonic reflectarray metasurface
In this paper, an electrically tunable reflectarray metasurface for two dimensional (2D) beam steering is designed by integration of a thin layer of indium tin oxide (ITO) material into a metalinsulator-metal (MIM) plasmonic unit-cell. The reflectarray is composed of square-shaped patch nanoantennas placed on a stack of insulator-ITO-metallic ground plane. The resonant characteristic of unit-ce...

This work presents a miniaturized lab-on-chip system suitable for monitoring the activity of living cells through the on-chip detection of their bioluminescence emission. The system integrates amorphous silicon diodes, acting as temperature and light sensors, and indium tin oxide film, acting as heater, on a single glass substrate. During its operation, the glass is thermally and optically coup...

High-quality and density-tunable GaAs nanowires (NWs) are directly grown on indium tin oxide (ITO) using Au nanoparticles (NPs) as catalysts by metal organic chemical vapor deposition (MOCVD). Au catalysts were deposited on ITO glass substrate using a centrifugal method. Compared with the droplet-only method, high-area density Au NPs were uniformly distributed on ITO. Tunable area density was r...
