We propose a rectangular liquid-infiltrated dual-core polymer optical fiber (POF) for short-range communication systems by the beam propagation method (BPM). The POF multi/demultiplexer (MUX/DEMUX) at the wavelengths of 0.52/0.65-m, 0.57/0.65-m, and 0.52/0.57-m are devised. The simulation results demonstrate that the ultrashort length of three ultrashort POF couplers are 183.6 m, 288 m, and 799.5 m. Compared with the conventional optical fiber couplers, these results could have significant applications in the miniaturization of optical devices for visible light communication.
