Design Optimize Interference Dielectric Edge Filter
Journal Title: INTERNATIONAL JOURNAL OF ENGINEERING TRENDS AND TECHNOLOGY - Year 2013, Vol 4, Issue 4
Abstract
An Edge filter is a multilayer coating with a substantial pass-band on either designated side of the stopband. The Edge filter is meant to have a crisp boundary between wavelength regions that are reflected and those that are transmitted. In this paper, design, optimize, and measurements of an Edge filter is presented. TiO2/SiO2 materials system provides a promising solution for realizing low cost lasers, detectors, and optical modulators operating in the telecommunications, by fabricating these devices on Fusedsilica substrates. An extensive comparison of the response obtained from initial design and the final optimization design is presented. In these study results we demonstrate a dielectric multilayer filter. TiO2 (refractive index n=2.346) and SiO2 (refractive index n=1.485) edge filter design with a controlled transmission, reflectivity, absorption, optical admittance, electric field, and dispersion in the wavelength range 300-1000nm.
