Three-dimensional photonic devices can process multiple signals simultaneously in terms of multi-dimensional space division multiplexing,which increase the transmission capacity and improve the integrated density.In this paper,based on selfimage principle of 3D Multimode Interference(MMI)coupler,a 3D Beam Splitter(BS)with mode conversion is designed,which can be easily integrated.The 3D-BS with mode conversion can convert the input beam at the fundamental mode into three output beams at the fundamental mode and three output beams at the first-order mode.The length,width and height of the MMI are designed with polymer materials and optimized to be 3 398.17,50.00 and 29.37μm respectively.The simulation results show that the total transmission efficiency of the BS is 85.5%,and the transmission efficiency of the output fundamental mode is 28.9% with the maximum imbalance of 0.010 dB.The conversion efficiency of the output first-order mode is 56.6% and its maximum imbalance is 0.004 dB.
