摘要

Based on the analysis of near-field evanescent wave in the total internal reflection, a LED model was proposed by placing an Ag grating in the attenuated length of the evanescent wave. The spectral properties of the model were calculated by using the finite difference time domain (FDTD) method. The light extraction efficiency of the model was obtained. The results show that the embedded Ag grating can couple the near-field evanescent wave to the propagation wave that can emit out of the LED chip, which lead to the enhancement of the light extraction efficiency of LED.
