Silicon-Based Dual Linear Polarizer Exploiting Quasi-Bound States In The Continuum
2023 Seventeenth International Congress on Artificial Materials for Novel Wave Phenomena (Metamaterials)(2023)
摘要
We present a theoretical and experimental demonstration of a single layer silicon-based metasurface able to convert any arbitrarily polarized incoming light into linearly polarized light. Our metasurface leverages the topological features of symmetry protected quasi-bound states in the continuum and shows an experimental extinction ratio of ~40dB for two linear cross-polarization excitations, paving the way for a novel class of ultra-compact multi-frequency linear polarizers.
