摘要
In this study, we present GaInN blue light-emitting diodes (LEDs) with microstructures of rods and lenses made using direct optical wiring (DOW) technology. DOW technology allows the fast and versatile formation of designed patterns on a flat surface of LEDs. These microstructures on the LED surface enable either control of the emission pattern or enhancement of light extraction from the LEDs. DOW LEDs with micro-rods show broad emission patterns with high off-surface-normal intensities. DOW LEDs with micro-lenses show enhanced light output power relative to that of a planar reference LED. Consequently, this approach appears to be highly attractive for various state-of-the-art LED applications.
