摘要：An optical waveguide provided with a slab waveguide, which has a plurality ofphase gratings arranged at a distance from each other in a direction substantially parallel

to a light propagation direction and diffracting propagated light and a plurality ofinterference regions arranged alternately to the plurality of phase gratings in thedirection substantially parallel to the light propagation direction and interfering the lightdiffracted by the plurality of phase gratings, and an arrayed waveguide whose end isconnected to an end of the slab waveguide at a position of a constructive interferenceportion of a self-image formed by the plurality of phase gratings as an integrated phasegrating.
