摘要

Narrow bandpass optical interference filters that precisely meet arbitrary Chebychev (equiripple) or maximally flat specifications are designed by refractive index refinement of standard multicavity filters, combined with straightforward manipulations of the solutions. The filters are composed mostly of quarter-wave (QW) layers of two materials. A few non-QW tuning layers are introduced in regions of the multilayer stacks that have a low sensitivity to deposition errors in order to control the passband ripple and halfwidth. Multiple solutions with exactly the same passbands are easily generated, from which those that have the best chance of being successfully fabricated can be selected.
