MicroLEDs offer a combination of high luminance, high energy efficiency, and long lifetime in a controllable light source. These characteristics are highly desirable in various applications, but usage has, to date, been primarily focused on next-generation display technologies. In non-display applications which use micro-LEDs as light sources, modifications in key electrical and optical characteristics such as external efficiency, output beam shape, modulation bandwidth, light output power, and emission wavelengths are often needed for optimum performance. A number of advanced fabrication and processing techniques have been used to achieve these electro-optical characteristics in micro-LEDs.

In this webinar hosted by the NonImaging Optical Design Technical Group, Ioannis Kymissis will review some non-display application areas of the micro-LEDs (including microscopy, optogenetics, and maskless lithography), the distinct opto-electrical characteristics required for these applications, and techniques that integrate the optical and electrical components on the microLEDs to improve system-level efficacy and performance. Work from both Dr. Kymissis’s group and the micro-LED community will be highlighted.

About the Presenter: Ioannis Kymissis from Columbia University 

Ioannis (John) Kymissis is the Kenneth Brayer Professor of Electrical Engineering at Columbia University and Chair of the Department of Electrical Engineering. He graduated with his SB, M.Eng., and Ph.D. degrees from MIT. His M.Eng. thesis was performed as a co-op at the IBM T.J. Watson Research Lab on organic thin-film transistors, and his Ph.D. was obtained in the Microsystems Technology Lab at MIT, working on field-emission displays. After graduation, he spent three years as a postdoc in MIT's Laboratory for Organic Optics and Electronics, working on a variety of organic electronic devices, and also as a senior engineer for QD Vision (later acquired by Samsung Electronics). He joined the faculty at Columbia University in electrical engineering as an assistant professor in 2006. He is a fellow of the IEEE, Optica, and the Society for Information Display (SID), and is currently the president-elect for SID.
