摘要
There is provided an optical waveguide comprising: a periodic component comprising a plurality of material elements (101) arranged to receive radiation; and a plurality of tapered waveguides (103), wherein each material element is respectively coupled to a tapered waveguide which tapers outwardly from the material element. The device works as a broadband absorber.
