An optical mode multiplexer was newly designed and fabricated using LiNbO₃ waveguides. The multiplexer consists of an asymmetric directional coupler capable of achieving the phase-matching condition by the voltage adjustment. The mode conversion efficiency between TM₀ and TM₁ modes was quantitatively measured to be 0.86 at maximum.
