Abstract:

Reduction of light reflections in substrate modes. The use of absorbing multilayer thin-film lither interference coatings on the backside of a LiNbO3 substrate provides and optical system which substantially reduces reflected substrate modes in integrated optical spectrum analyzers at around 8300 angstroms wavelength, or at other selected wavelengths, over a broad range of incident angles by selection of individual film thickness and optical constants.
