Abstract: Experiments were performed to research the electrooptical characteristics of holographic polymer dispersed liquid crystal (HPDLC) at 1 550 nm. Results showed that the frequency and amplitude of the applied field impact the
diffraction efficiency and transmission efficiency of HPDLC greatly. The theory
of dielectric matters was used to explain the relationship between the
applied field frequency and the dielectric constant and how it influences the
effect of electrooptical modulation of the HPDLC. It was proved that the HPDLC devices are potentially useful for Erbium doped fiber amplifiers as a
tunable gain equalizer.
