Abstract

An array waveguide grating (AWG) device in which at least one additional waveguide (24) is provided for each input waveguide of the AWG. The or each additional waveguide is optically coupled to the first free space coupler (22) and disposed adjacent to the respective input waveguide (20). In some described embodiments, one or two such additional waveguides are provided adjacent to each input waveguide and have a tapered shape designed to transform adiabatically the a single peak field in the input waveguide to a multiple peak field which produces a flattened passband at the AWG channel outputs. The additional waveguides can alternatively be provided at the output side of the AWG. Also claimed is an optical power splitter based on the same adiabatic mode shaping structure.
