Experiments were performed to research the electrooptical characteristics of holographic polymer dispersed liquid crystal (HPDLC) at 1 550 nm. Results showed that the frequency and amplitude of the applied field impact thediffraction 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 electrooptical modulation of the HPDLC. It was proved that the HPDLC devices are potentially useful for Erbium doped fiber amplifiers as a tunable gain equalizer.
