Abstract
An optical grating being formed by a waveguide branching structure having a single infeed end face for infeeding an optical wave to be coupled into the grating, said branching structure is composed of a strip-like optical waveguide that proceeds from the infeed end face in a tree-like branching fashion and ends at the outfeed end faces, the distance between the infeed end face and each of the outfeed end faces can be the same or be different, as desired. The outfeed end faces can also be arranged to extend obliquely to the propagation direction of the optical wave being propagated in the grating.
