Ultra-Narrowband High-Transmissivity Guided-Mode Resonance Filter Based on Dual Dielectric Film Structure and High Refractive Index Waveguide Layer
In this study, we propose a novel approach to achieve an ultra-narrow bandwidth and high transmittance filter in the visible range. By employing TiO<sub>2</sub> as the waveguide layer material, the coupling energy in the waveguide layer is enhanced, leading to a reduction in the full wid...
