A Broadband Polarization Splitter Directional Coupler Based On Tilted Subwavelengh Grating Metamaterials
2020 IEEE PHOTONICS CONFERENCE (IPC)(2020)
摘要
Tilted subwavelength gratings (SWG) allows anisotropy tailorable metamaterials with applications in polarization management. Based on this concept, here we experimentally demonstrate a broadband directional-coupler-based polarization beam splitter with sub-decibel insertion loss in a 100 nm bandwidth.
