Design and fabrication of a high transmissivity metal-dielectric ultraviolet band-pass filter Academic Article uri icon

abstract

  • We introduce an efficient design approach for Ultraviolet (UV) band-pass filter based on metal-dielectric stacks. We present a general design method and then apply this design to two special cases: a UV band pass filter based on (i) Al/Al2O3stacks as well as (ii) Ag/SiO2stacks. As an experimental confirmation, we fabricate a UV filter with three Ag/SiO2layer pairs on a fused silica substrate (Corning 7980), targeting a central wavelength of 320 nm. A measurement at the peak wavelength shows transmission efficiency as high as 67% in our filter. 2013 AIP Publishing LLC.
