We show that it is possible to obtain 2×2 waveguide couplers with arbitrary power splitting ratios by interconnecting a pair of unequal-width waveguides as the phase-tuning section into the middle of two short MMI sections. These couplers have simple geometry and low loss. They offer valuable new possibilities for designing waveguide-based photonic integrated circuits.
