Enhanced light extraction of micro-pixelated LEDs by arc-shaped mesa sidewall
The micro-structuring of heterostructure layers is an efficient method to enhance the light extraction efficiency of light emitting diodes (LEDs). The light extraction efficiency of micro-pixelated LEDs emitting at 230 nm with arc-shaped mesa sidewalls has been studied by Monte-C...

Influence of Photonic Crystal Size and Lattice Constant on the Lasing Performance of UV-C PCSELs
Abstract Semiconductor lasers are compact, high-power coherent light sources across a broad wavelength range in the electromagnetic spectrum, including visible and infrared. Despite significant progress, they have yet to achieve the same performance for ultraviolet-C (UV-C) wavel...
