Abstract

See full text

A grating structure has a plurality of gratings. In one example, one or more of the gratings are configured: to be non-uniformly spaced with respect to one or more other ones of the gratings; and to optically couple a first light conduit and a second light conduit enabling light having a first polarization and light having a second polarization to pass through the grating structure and propagate in the same direction in the first light conduit or the second light conduit. The non-uniform spacing of the gratings may represent an intersection or a union of a period associated with the light having the first polarization and a period associated with the light having the second polarization.
