Abstract

Aiming at the non-linear dispersion of single grating dispersive device, in this paper, a novel dispersive device based on volume holographic multiplexing storage principle is reported. According to this principle, more than one volume holographic gratings are recorded in the same photorefractive material. The Bragg wavelength selectivity of volume hologram indicates that a volume holographic grating (VHG) with certain thickness can have definite diffraction efficiency only under the design center wavelength. Therefore, in order to make the whole device realize the needed distribution of spectral lines, a number of VHGs must be multiplexed on the device and each volume grating is corresponding to variant center wavelength. This multiplexing volume holographic dispersive device (MVHDD) can be realized by means of wavelength-angle mixed multiplexing recording (WAMMR). Through adjusting recording parameters of each VHG and multiplexing number, all design center wavelengths can be reasonably distributed in operating spectrum coverage, accordingly the dispersive characteristic of the MVHDD can be reasonably determined. On the base of coupled wave theory, this paper describes spectral characteristics of the MVHDD, discusses the relation between the main parameters of spectral device and the recording parameters of WAMMR, and then gives results of theoretical analysis.
