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.
