title: Rugate filter sidelobe suppression using quintic and rugated quintic matching layers.
abstract: Sine wave rugate index profiles may be superimposed on a slowly varying average index in such a way as to reduce sidelobes over broad spectral regions and at the same time maintain the strength of the stopband reflectance.
