Abstract
An optical device may include a substrate; an arrayed waveguide grating provided on the substrate and having first and second slabs; multiple first waveguides extending from the first slab, the multiple first waveguides may supply respective first optical signals to the first slab; multiple second waveguides extending from the second slab, the multiple second waveguides may supply respective second optical signals to the second slab; a third waveguide extending from the second slab, the third waveguide outputting a third optical signal from the second slab, the third optical signal including the first optical signals; a fourth waveguide extending from the first slab, the fourth waveguide may output a fourth optical signal from the first slab, the fourth optical signal including the second optical signals; and a first scattering device optically coupled to a portion of an edge of the first slab between the multiple first waveguides and the fourth waveguide.
