Abstract
We designed and fabricated porous silicon-based broadband rugate filters by combining up to five rugate structures. A near-infrared stop-band filter having a reflection band width of 1356 nm with no higher-order harmonics and very small sidelobes were realized. The suppression of higher-order harmonics and the reduction of sidelobes also allowed us to produce a high quality pass-band filter exhibiting a high transmittance region sandwiched by two broad stop-bands.
