摘要：

We proposed a broadband 3-dB power splitter based on multimode-interference coupler formed by polymer waveguide, which is insensitive to the arbitrary input modes, and demonstrated the operation functions of the design in the experiment. The design shows a mode-insensitive 3-dB power splitting for the E11, E21 and E12 modes with an imbalance power less than 0.11, 0.13 and 0.03 dB, respectively, over a 100 nm bandwidth that ranges from 1520 to 1620 nm. Our presented mode-insensitive 3-dB power splitter could find applications in mode (de)multiplexing systems where ultra-broadband power splitting is required.
