Abstract

The diffraction of volume holographic gratings follows the Bragg law, and narrow wavelength selectivity and angle selectivity can be achieved with certain thickness of hologram. Multiple volume holographic gratings formed in Fe : LiNbO3 have high diffraction efficient and stability performance, which can be used for compact dense multiplexer/demultiplexer (MUX/DMUX). In this paper, we identify that it is feasible to record 16 volume holographic gratings by a special recording ways. The calculated results show the insertion losses and crosstalk at 1 .55µm waveband with channel separation 0.8nm is 0.66dB and —26dB respectively.
