DOI: 10.1364/ol.44.003598
Abstract: Fabrication, characterization, and analysis of an ultrabroadband lithography-free absorber is presented. An over 94% average absorption is experimentally achieved in the wavelength range of 450-1400 nm. This ultrabroadband absorption is obtained by a simple annealed trilayer… read more here.
