In this paper a novel grating-like integrated optics device is proposed, the CrossWaveguide Grating (XWG). The device is based upon a modified configuration of a traditional ArrayedWaveguide Grating (AWG). The Arrayed Waveguides part is changed, as detailed along this document, giving the device both the ability of multi/demultiplexing and power splitting/coupling. Design examples and transfer function simulations show good agreement with the presented theory. Finally, some of the envisaged applications are outlined.
