Abstract
An InGaAsP/InP variable power splitter utilizing the multimode interference (MMI) and the linear electro-optic (LEO) effect is designed and analyzed. The splitter consists of two MMI waveguides and phase-shifting waveguide section between them. The input MMI waveguide acts as a 3-dB splitter for the TE input signal. In the phase-shifting waveguides, the relative phase of split input signals is changed by using the LEO effect. The output MMI waveguide combines the phase-modulated signals at output ports. Depending on the amount of phase change induced by reverse bias voltages of 0 approximately 2.5 V, the splitting ratio varies from 100(DOT)0 to 50:50 continuously.
