Abstract

We report on the development of a metasurface-based infrared sensor using Dolmen plasmonic nanostructures. The metasurface is designed to resonantly enhance the absorption of infrared light at a specific wavelength. The sensor is designed and optimized for high sensitivity and selectivity in the infrared region. This simple metasurface sensor is a promising platform for various applications, such as gas sensing, biosensing, and security. The optimized design is easy to fabricate and compact. The fabrication tolerance is also studied to ensure the good reliability of the sensor. The sensor achieves a sensitivity of 530 nm/RIU.
