Biphasic micro-LED driver for optogenetics
2016 IEEE Biomedical Circuits and Systems Conference (BioCAS), 2016Optogenetics is a gene-therapy technique which utilizes high radiance light to stimulate the genetically modified nerve cells. An optical delivery method in brain tissue for optogenetics can be performed using incorporated micro-LEDs. Optrode lifespan can be affected by the electrodes degradation caused by the generated charges over the tissue after ...

Development of Micro-LEDs and Applications
2019 IEEE Photonics Conference (IPC), 2019Since our invention in 2000 [1–4], microLED has emerged as a promising technology for a range of applications. MicroLED can provide much higher brightness levels than those of LCD and OLEDs. Therefore, microLED arrays are ideal for self-emissive microdisplays [3–9] and ultrahigh brightness and resolution large flat panel displays [9].

Fluorescence imaging device with an ultra-thin micro-LED
2017 IEEE Biomedical Circuits and Systems Conference (BioCAS), 2017In this work, we designed and fabricated an image sensor with an ultra-thin light-emitting diode (LED). The chip has areas with a metal shield for LEDs. An ultra-thin LED fabricated using the laser lift-off technique was mounted on the chip. Excitation and emission filters based on absorption dye were applied to the LED and the pixel array.

Optical spatial modulation OFDM using micro LEDs
2014 48th Asilomar Conference on Signals, Systems and Computers, 2014This paper investigates the performance of optical spatial modulation (OSM) with orthogonal frequency division multiplexing (OFDM) in a multiple-input and multiple-output (MIMO) based visible light communication (VLC) system. Gallium nitride micro light emitting diodes (μLEDs) are used as transmitters. The performance of the OSM-OFDM system is analyzed
