[10p-N404-8] Silicon Perfect Absorber of Quadrupole Modes within the visible light range

All-dielectric perfect absorbers based on degenerate critical coupling can overcome the absorption limitation of an ultra-thin freestanding layer. In addition to dipole modes, we find that the concept of degenerate critical coupling applies to quadrupole modes of Mie resonators. Herein, we design a silicon perfect absorber of quadrupole modes based on degenerate critical coupling.
