The purpose of this thesis is to create a model for designing optical filters and a method for fabricating the designed filters onto a multitude of substrates, as well as to find ways to optimize this process. The substrates that were tested were quartz, glass slides, polycarbonate, and polyethylene terephthalate (PET). This work will account for variations in the deposition process and substrate cleaning method, in order to optimize the performance of the final optical filter. Several different filters were simulated and then fabricated. These filters included 3, 5, and 7-layer Bragg reflectors, 11-layer narrowband filters, and some variations of the 11-layer narrowband filter where the center layer is adjusted. This paper will highlight the steps involved in designing and simulating these filters, the steps involved in testing and optimizing their fabrication processes, and the tests and measurements determining their effectiveness. The effectiveness of the filters is determined by how high their maximum reflectivity and transmittance are, and in the case of narrowband filters by the width of the transmittance peak’s full width half max (FWHM).
