ABSTRACT:
An optical coupling device for coupling a light beam into a waveguide and a method of manufacturing the device. The device includes a grating portion having a plurality of essentially straight and essentially parallel scattering elements, wherein two or more of the scattering elements have different lengths. The method includes providing a grating layer on a substrate and forming a plurality of essentially straight and essentially parallel scattering elements from the grating layer, wherein two or more of the scattering elements have different lengths.
