Analytical formulas for combinations of cavity size, material texture and incoming angle are given so that the filtering purpose is optimally served. In this way, inverse design for a simple class of optical setups is rigorously performed and, if the employed medium is very dense and the working band narrow enough, sharp filters with increased frequency selectivity are obtained.enAttribution-NonCommercial-ShareAlike 3.0 United StatesFabry-Perot interferencephotonic filterinverse designResearch Subject Categories::NATURAL SCIENCESArticle
