Abstract: | A photonic crystal waveguide coupling structure can be constructed by putting three adjacent photonic crystal waveguides in parallel. Guided mode propagation method is employed to analyze the interference behavior of the approximate solution in such a coupling and the self-image phenomenon in multi-mode waveguides. A three-channel multimode interference wavelength division multiplexing can be obtained. The presented device has a high transmission rate as well as the advantage of multi-wavelength selection, thus it may have a potentially practical application in future photonic integrated circuit. |
