A multi-mode interference (MMI) GaAs 1×4 optical p ower splitter that can be directly coupled with single mode fiber array was fabr icated through optimized structure design and preferential etching. The 1.3 μm He-Ne laser measurement indicated that the device has basically realized the re quirement of uniform power splitting
