| Abstract(in English) | A novel wavelength demultiplexer and wavelength division optical switch using arrayed waveguides with staircase-like refractive index distribution by MOVPE selective area growth has been proposed. By placing the asymmetric width of SiO_2 mask pattern on both sides of the arrayed waveguide, the thickness of the each waveguide in the array has changed gradually. The refractive index of these arrayed waveguides are different from each other, and the light suffers a phase difference in the propagation of the arrayed waveguides. These arrayed waveguides can be used for wavelength demultiplexer consisting of only straight arrayed waveguides, and analyzing the wavelength switching by using the dynamic refractive index change in the waveguide. We show the application for the wavelength division optical switch. We have numerically calculated the wavelength dividing and switching performance of this device. Moreover, the successful fabrication of the proposed arrayed waveguides by using MOVPE selective area growth is shown, and the primitive demultiplexing of wavelength in these waveguides have been achieved. |
