High-Performance Broadband Silicon-Based Photodetector Enabled by Biomimetic Asymmetric Metasurface
Through millions of years of natural evolution, the crystalline cones of moth ommatidia have developed highly complex and precisely arranged microstructures. These structures play a crucial role in light transmission, reflection, and refraction, endowing moths with unique optical properties. Inspired by this natural phenomenon, metasurface units have successfully mimicked and optimized these optical performances through precise artificial design and fabrication. In this study, we utilized bound states in the continuum to develop a high-performance Si-based photodetector with broadband photoresponse (300-1600 nm), maintaining high responsivity and specific detectivity even at 1550 nm. This interdisciplinary fusion and innovation have not only driven advancements in the field of optoelectronic devices but also opened new avenues, creating opportunities for technological progress across various domains.
