| Abstract(in English) | A novel wavelength demultiplexer and wavelength division optical switch using arrayed waveguide wiih linearly varying 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. A wavelength demultiplexer using arrayed waveguides in which refractive index varies linearly across the devices was investigated and successful fabrication of GaloAs/InP MOW arrayed waveguide devices was achieved. A straight arrayed waveguide device with a approximate 1.4 % refractive index difference was fabricated using an asymmetric side mask of width 200 fxm by MOVPE selective area growth. The achievement of a diffraction angle difference of 4.40^o between 1520 nm and 1580 nm wavelength was then confirmed in "he measurements of diffraction patterns in the Fresnel region of the devices. |
