Design of an Integrated Circularly Polarized HgCdTe Photodetector Based on Silicon Metasurfaces
Compared with conventional detectors, a circularly polarized detector operating at 4.26 μm effectively suppresses background noise (e.g., solar scattering and atmospheric interference), enabling high-precision CO<sub>2</sub> monitoring across ecosystems like farmland, forests, and wetlan...
