Design and Fabrication of Extended-Bandwidth Rugate Filters Made of Porous Silicon
We designed and fabricated porous silicon-based broadband rugate filters by combining up to seven rugate structures. A near-infrared stop-band filter having a reflection band width of 1926 nm with no higher-order harmonics and very small sidelobes were realized. The suppression of higher-order harmo...
