  • Dichroic filters formed using silicon carbide based layers
    Patent number: 8481109
    Abstract: The present invention provides a method of forming a flexible dichroic optical filter. The method comprises depositing a plurality of pairs of layers adjacent a substrate. Each of the plurality of pairs of layers includes a first layer formed of a silicon-and-carbon containing material having a first index of refraction and a second layer formed of a silicon-and-carbon containing material having a second index of refraction that is different than the first index of refraction.
    Type: Grant
    Filed: August 6, 2008
    Date of Patent: July 9, 2013
    Inventors: Ludmil M. Zambov, Vasgen A. Shamamian, Jeffrey A. Seifferly, Susan V. Perz
