title: Nonlinear holography: a novel approach for creating near-infrared narrow-notch reflectors.
abstract: It is shown that the nonlinearity in the response function of a holographic medium can lead to formation of gratings at the sum and difference frequencies of the exposing standing-wave patterns. This nonlinear feature can be utilized to create reflection holograms at spectral regions where conventional techniques are not applicable. Specifically, it is suggested that near-infrared or infrared rejection filters that are sensor centered can be obtained by using this approach.
