Dual-Mode High-Q Multiphysics Sensor Based on the Evanescent Wave in the InSb Photonic Crystals

Boosting of the terahertz absorption spectrum based on one-dimensional plastic photonic crystals

“…21 However, the coated samples on metasurfaces or metagrating are usually not uniform because of the complex unit cell structure. The ideal substitute enhancing structure is the 1D photonic crystal (PC), which has been widely used to design micro-and nano-devices, such as sensors, 22,23 , semiconductor lasers, optical switches, and others. As one of the important means of electric field localization, the defect one dimensional (1D) photonic crystal structures have been widely used in refractive index sensing in the terahertz band.…”
