Ultra-broadband, lithography-free, omnidirectional, and polarization-insensitive perfect absorber
Abstract Perfect absorbers (PAs) at near infrared allow various applications such as biosensors, nonlinear optics, color filters, thermal emitters and so on. These PAs, enabled by plasmonic resonance, are typically powerful and compact, but confront inherent challenges of narrow bandwidth, polarizat...
