The multimode interference 1 × 4 optical power splitter was designed by guided mode transmission analysis. According to the determined structure parameters of the device and the factors that may be encountered in the design and fabrication of the device, the influences of the self-imaging multimode waveguide width and length, the refractive index of the waveguide and other structural parameters on the performance of the device are analyzed in detail. The fabrication and testing of multimode interfering Ga As 1 × 4 optical splitter were carried out. The test results show that the device developed by the 1 × 4 optical power splitter function. The problems encountered in the experimental process and the test results are discussed, and the method to further improve the performance of the device is proposed.
