Tailoring a Plasmonic Topological Architecture for a Hyperspectral Resolution Pyroelectric Detector

factor of 1168, far surpassing the level of ordinary plasmonic metasurfaces. Furthermore, the wavelength and width of its response peak can be continuously engineered by controlling the period and orientation angle of the architectures, while its response speed is also improved significantly with the assistance of a plasmonic topological layer. Our work provides a concise and effective strategy to develop hyperspectral resolution photodetectors without inherent constraints of materials and wavebands.
