Angle-independent micro-OLED cavity via phase-compensating plasmonic resonant metasurface

초록

This study focuses on optimizing a Metal-Insulator-Metal (MIM) OLED structure as a plasmonic absorber for advanced micro-display applications. The MIM structure enhances the localized electromagnetic field and improves stability against refractive index variations in the planarization layer during fabrication. The optimization process involved 2D Rigorous Coupled-Wave Analysis (RCWA) simulation to identify resonant modes and parameter dependencies in nanostripe metasurfaces. Additionally, angle-resolved simulations were conducted to observe the spectra response under varying incident angles, demonstrating superior angular sensitivity at zero degrees compared to traditional cavity structures. Results show the MIM structure's superior stability and performance, maintaining consistent resonance conditions despite variations in the planarization layer. This makes the MIM-based approach ideal for high-precision micro-OLED applications.
