A tunable filter based on dynamic holographic recording in BaTiO3 is described. A selectivity of the filter of 0.1 nm and a tuning range of not less than 100 nm have been obtained. The transformation of the stop band filter transfer function into the pass band transfer function has been demonstrated in real time. A theoretical description of the transfer function of the filter with the grating phase jump is given.
