Power splitters based on multimode interference (MMI) devices that offer the possibility of dynamically tuning the power-splitting ratio using electro-optic (EO) polymers are presented. The so-called 1 × 2 electro-optic MMI (EO-MMI) is demonstrated to provide a tuning range of 6   dB at 54   V as theoretically predicted. Also a method is discussed to reduce the driving voltage by generating multiple beats, which provide 15 V for a tunable range of 10   dB for r 33 = 15 pm / V at wavelength 1.55 μ m .
