Abstract
We present two applications of volume holographic filters in the reflection geometry. A passive athermal holographic filter design is realized through the mutual compensation between the temperature coefficients of the bulk hologram and a variable incident angle controlled by a bimetallic cantilever. Seven holograms are multiplexed to constitute a multi-line filter which can be used to emulate specific absorption or emission spectra for spectroscopic applications.
