We propose a rewritable optical frequency filter based on a volume Bragg grating recorded by holography on an SBN:75 photorefractive crystal. The theoretical results show the possibility of implementing a narrow-band filter whose reflectance is total for the characteristic wavelength of the third harmonic of the infrared for both TE and TM polarizations by optimizing the size of the interference fringes and the angle of incidence of the beam to be filtered, which must be close to 80 degrees.
