Abstract

Optical interference filters were fabricated using multilayers derived from sol-gel SiO₂ and SiO₂-TiO₂ thin films. Laser processing was then used to modify the spectral properties of local regions of these stacks. The feasibility of using laser processing for selectively changing the optical properties of thin film devices was thus demonstrated. Design considerations and some basic limitations of this technique for tuning interference filter colors are then discussed.
