Paper Abstract

According to coupled wave theory, when a volume holographic grating (VHG) is used as dispersion device, the Bragg wavelength selectivity indicates that only in narrow spectrum range can VHG have definite diffraction efficiency. Therefore, volume holographic dispersive device with broad spectral coverage can be realized by means of multiplexing. The key technique is based on wavelength multiplexing holographic recording. Each VHG is corresponding to a narrow spectral range with variant center wavelength. In this paper, the Bragg compensatory multiplexing recording (BCMR) is reported, which can realize multiplexing volume holographic device written with a single wavelength and working under multi-wavelength without using a tunable laser. This key technique can be realized based on the reciprocally compensatory relationship between the wavelength of incident light and the Bragg angle when Bragg matching. In this paper, a BCMR experimental system is constructed to prove the practicability of this recording method.
