Theoretical and experimental investigations of electric field multiplexing
and selectivity of reflection volume holograms in LiNbO3 are reported. Reco
rding of at least five holograms is demonstrated. Equivalent spectral selec
tivity Delta lambda approximate to 4.5 pm for the case of three electricall
y tunable holograms and Delta lambda approximate to 9 pm for the case of fi
ve electrically tunable holograms are estimated.
