100 THz bandwidth all-optical switching using coherent absorption in plasmonic metamaterials

100 THz bandwidth all-optical switching using coherent absorption in plasmonic metamaterials
100 THz bandwidth all-optical switching using coherent absorption in plasmonic metamaterials
Using femtosecond laser with variable pulse duration we probe the limits of switching that exploits coherent absorption in nanostructured gold films. Switching contrast ratios of 7:1 with a modulation bandwidth exceeding 100 THz has been observed.

Abstract

Using femtosecond laser with variable pulse duration we probe the limits of switching that exploits coherent absorption in nanostructured gold films. Switching contrast ratios of 7:1 with a modulation bandwidth exceeding 100 THz has been observed.
