Abstract
In this paper, the chirp volume grating recorded in photopolymer for the optical demultiplexer is presented. By using the chirp grating, the spatial distance of fibers can be controllable. The chirp rate of the grating is investigated. As a result of the experiment, a 51-channel 0.4-nm-spaced demultiplexer with the channel uniformity of 3.5 dB, the 3dB-bandwidth of 0.12 nm, and the channel crosstalk of -20 dB is experimentally achieved.
