Abstract

Abstract

We present a tracking and alignment capability for use in mask-less lithography systems. Through the use of micropixellated light emitting diode (LED) arrays, fluorescent clusters can be identified and used as alignment markers at micrometer scale.

Abstract

Abstract

We utilize a rate equation approach and RF measurement technique to study carrier dynamics in InGaN/GaN LEDs. Study of carrier dynamics aids in understanding efficiency challenges and design of high-speed, efficient micro-LEDs for visible-light communication and micro-LED display applications.

Abstract

Abstract

Integrated blue-violet and blue-green micro-LED arrays, fabricated via a transfer printing method, were employed to demonstrate wavelength division multiplexing underwater data transmission at 100 Mb/s over up to 9 attenuation lengths in a 1.5 m long water tank.

Abstract

Abstract

This talk will describe nanowire-mediated formation of microLEDs via controlled reshaping of ternary InGaN pyramids yielding c-oriented InGaN-platelet microLEDs emitting all three RGB-colors. I will also describe recent progress in the self-formation of atomically smooth and dislocation-free hexagonal prism structures acting as photonic cavity structures.
