Abstract
Equiripple bandpass interference filters are designed by the refinement of a few layers of standard QW multicavity designs, and some simple manipulations of the solutions. Ways to control the intermediate refractive indices of the running layers, and/or their non-QW optical thickness, are described. Some limitations of earlier approaches are avoided.
