PROTOTYPICAL SIMULATION OF AN OPTICAL EDGE FILTER DESIGN FOR THREE DIFFERENT RAYLEIGH WAVELENGTHS USING OCTAVE SOFTWARE
Over the past few decades, researchers have worked hard to create optical filters that let some wavelengths through but block others. Multi-coated optical screens are becoming more popular. Layer thickness changes the functionality of these filters, giving them several uses. Quarter wave stack (QWS) technique makes edge filters and other optical filters. Optimization is needed to meet minimal standards. The QWS model and Octave's optical matrix technique will be used to create an optical edge filter. The design used Si and MoS2, both low- and high-refractive-index materials. The results show 24 layers is best. Increased transmittance allows this. The design modeling employed "glass|12HL|air." for the 405 nm, 532 nm, and 633 nm (ex) Rayleigh wavelengths. After building and testing the optical edge filter, Cuton and Cutoff values are found. Three cut-on frequencies are detected at 408.11, 536, and 640.25 nm. The three matching activities had MET values of 32.3%, 31.3%, and 32%. This research demonstrates that the predicted value and model differ by 0.2, 1.7, and 1.15 nm for the three ex values (405, 532, and 633 nm). While the estimated value is lower, the Cutoff figures are substantially higher. Some filters show 32% modulation transfer efficiency (MET) at the Rayleigh wavelength, whereas others show 32.3%, 31.3%, or 32%.
