A novel power splitter based on self-imaging phenomena in multimode heterostructure is designed and analyzed. Such a photonic crystal waveguide is a hybrid structure combining square and hexagonal photonic crystal lattices. The size of our designed new power splitter is much smaller in comparison with the conventional MMI power splitter. The devices can be applied to optical communication systems and be integrated easily with other optical devices. The plane-wave expansion (PWE) method is used to calculate the bandgap structure of photonic crystals. The finite-difference time-domain (FDTD) method is adopted for the numerical simulation of related structure. This approach can be extended to novel design of MMI device based on photonic crystals.
