Abstract
Here we present a FDTD modeling and simulations study to show that introduction of two dimensional Photonic Crystal slabs is very promising method to improve the light extraction from OLED devices. In this present work a 2D FDTD simulation using Lumerical FDTD solutions software is carried out for TE polarizations and we investigate and compare two different materials choices: SiN-Spin on Glass (SOG) and ZnO-Polycarbonate which are based on two different paths of RIE and Sol–gel process to form the Photonic crystals embedded OLED and make an attempt to conclude which is better option for mass manufacturing possibilities with OLED devices for improved extraction.
