Based on analysis of light propagation in multiple cavity aperiodic structures, a filter with three narrow passbands with high transmission is designed. The design is implemented for use in express early-stage oral cancer screening by means of Raman spectroscopy. A combination of SiO2/Nb2O5 is used in a vacuum deposition process to ensure high refractive index contrast and durability of materials. The approach enables the development of simple and affordable Raman testers for multiple medical, forensic, and environmental applications.
