Polymer optical fiber (POF) in one of the best transmission media for shortidistance communications. To increase the transmission capacity of the fiber a wave lenght-division-multiplexing (WDW) technique is commonly used. Several POF-WDW systems have been realized using interference filters and plane diffraction gratings as wavelenght selective elements. In the present paper, for the first time a concave diffration grating is applied with POF. A holographic concave grating is calculated and optimized for the use in an optical demultiplexer. The optical losses in the designed demultiplexer are estimated theoretically.
