Abstract :
This paper presents optical filters for integration on stereoscopic image sensors. The filters must cover each one of primary colors within the visible, in order to yield a passband around the respective wavelengths. Dielectric materials based on SiO2 and TiO2 were used due to their compatibility with silicon. The best simulation with only 3 dielectric layers resulted in optical filters with full width at half maximum (FWHMs) of 79, 95 and 124 nm and central wavelengths of 456, 529 and 605 nm, respectively.
