Broadband dielectric film transflector for variable transmission optical filters
Abbreviated Journal Title
Transflector; Optical filter; Variable transmission; Optics
A broadband multilayer dielectric film transflector for applications in variable transmission optical filters is proposed. The dielectric film is composed of alternating TiO(2) and SiO(2) layers deposited on a substrate. The transmittance of the dielectric film transflector can be varied from 0 to 100% by adjusting the individual dielectric layer thickness and the number of layers. The conjugate gradient method is used to optimize the design of the transflectors. The obtained transflectors have good transmittance and reflectance within the whole visible range and the incident angle range 0-20 degrees. The manufacturing tolerances on film thickness and refractive index are reasonably large. (c) 2010 Elsevier GmbH. All rights reserved.
