Design optical filters using two different synthesis approaches

It is difficult to find any modern optical system that does not havecomponents with single or multiple layers of optical coatings, scientistsand engineers use optical coating filter based on the interference propertyof electromagnetic wave to achieve a desired reflectivity of light over arange of frequencies.In this paper we propose a two different efficient methods, needleoptimization method and genetic algorithms (GAs), for synthesis opticalcoatings. The task was to overcome the difficulty to obtain high qualitycoatings, with optical constants and low number of layers anddemonstrate that a highly efficient global optimization of optical filter canbe performed. Results includes the comparison between the results needleapproach in frame Open Filter (new software) and the results of geneticalgorithm technique , it is considered the first comparison between OpenFilter and (GAs). In addition they show us the advantage anddisadvantage of each approach in design high reflection optical filter
