فيزيك

This research presents a specialized software tool designed an‎d implemented for the simulation an‎d optimization of optical interference filters, utilizing the transfer matrix method (TMM). Interference filters are critical components in optical systems, including spectral filters, optical communication devices, an‎d precision optical instruments. The optimal design of these multilayer structures requires a comprehensive analysis of thin-film behavior under incidence of plane waves, which is effectively achieved through matrix-based modeling. The developed software enables accurate simulation of the spectral response of multilayer structures, optimization of layer thicknesses, an‎d eva‎luation of the impact of various design parameters. Key features of the tool include full user control over input parameters an‎d support for advanced optimization algorithms, such as genetic algorithms. Additionally, the software facilitates electromagnetic field analysis within the structure to enhance the laser-induced damage threshold (LIDT) by optimizing internal field distribution. Comparisons between the simulation results an‎d both theoretical predictions an‎d experimental data confirm the high accuracy an‎d reliability of the computations. Thus, this software serves as an efficient an‎d robust platform for the rapid an‎d precise design an‎d analysis of optical interference filters, making it a valuable resource for researchers an‎d optical engineers.
