Wavelength demultiplexing and wavelength switching are numerically calculated. The wavelength dependent power from the output ports are calculated by considering the phase in the variable index arrayed waveguide, and the diffraction in the rowland circle slab waveguide.


Furthermore, wavelength switching, demultiplexed lights are switched between output ports by changing the refractive index in the array waveguides, is numerically analyzed. We have obtained 24 pattern wavelength switching in the 4 output ports for 4 wavelength lights.
