“…In Section 2 we describe an efficient global optimization algorithm that has been successfully tested for CM design. One of the main problems with optimization of multilayer dielectric coatings is that the merit function usually has many local extrema, 21 so there is always a risk that a local optimization routine will get stuck far away from the best extremum. Global optimization was recognized long ago as a solution to this problem.…”

“…Global optimization was recognized long ago as a solution to this problem. There have been many successful attempts to apply global optimization algorithms to optical multilayer structures, [21][22][23] but there is one common problem: All known global optimization algorithms demand a large number of evaluations of the merit function, and the optimiza-tion process is thus often extremely time consuming. Here we show how the so-called memetic algorithm 24 can be utilized for relatively fast global optimization of chirped mirrors.…”

A large number of parameters is often required to describe optical dispersion laws, and it is only through the use of an appropriate global optimization procedure that an accurate thin film index determination can be achieved. In this paper, we propose to investigate the respective performances of three different optimization algorithms, namely Simulated Annealing, Genetic Algorithm and Clustering Global Optimization and compare results with a commercial software dedicated to thin film index determination. This study refers to the single layer and multilayer thin film index determination. It includes the theoretical study of simulated reflection and transmission spectra, and the experimental characterization of Ta 2 O 5 single layer and Ta 2 O 5 /SiO 2 multilayer.

“…The use of local minimization algorithms is efficient only if we have a good starting solution. For this reason we have further developed the simulatedannealing method [2,6]. This method uses the "Metropolis" algorithm [9], which is a Monte Carlo algorithm that generates a sequence of states converging asymptotically towards the Boltzman distribution.…”

The design concept of the required optical filters for the Fluorescence Detector of the AUGER Project, is presented in this work. Due to the needed high transmittance values in the UV region, the dielectric thin film multilayer technique, using UV-transparent materials, has been selected. The design method applied, is the "Monte Carlo Simulated Annealing" (MOCASA). Two alternative target spectral transmittance curves have been considered, as candidate for the optical filters. These are, the single-band pass and the multiband pass type, both covering the atmospheric nitrogen fluorescence spectral range. The design performance calculation, is based on the expected signal and the moonless night-sky background photon rates, selected by the optical filters. Characterizations of simple and double layres, using various candidate materials, are in progress, planning to produce a full prototype in near future.
