Abstract
In this work, we show on theoretical modeling of light-emitting didoes (LEDs) with antireflective subwavelength structures (SWSs) for enhanced light extraction efficiency and uniform field distribution. Theoretical analysis and geometrical optimization of SWSs are described based on rigorous coupled-wave analysis (RCWA) and finite-difference time domain (FDTD) methods. The results show the effect of period of SWSs on the extraction efficiency and field distribution.
