PROJECT TITLE :
Experimental Evidence for Coherent Perfect Absorption in Guided-Mode Resonant Silicon Films
We tend to experimentally verify a replacement category of coherent absorbers based mostly on guided-mode resonance effects in periodic skinny films. We tend to style a silicon-based mostly resonant absorber that is fabricated and tested close to the 130zero-nm wavelength. Implementing part management, the device can, in principle, be switched between full absorption and full scattering. The primary experimental prototype presented herein shows ∼78% absorption in the in-section state. Nearly total scattering is realized within the out-of-phase state. The experimental results agree fairly well with theory.
