An antenna device for performing off-chip light coupling comprising an array of radiating elements whose thickness is larger than λ/2, the radiating elements being chosen such that the length of the array is smaller than 10λ, where λ is the wavelength of light in the material chosen for the radiating elements. An advantage of this method is that, unlike in conventional waveguide grating antenna, by reducing the number of the radiating elements in the array, the dependence of the off-chip emission angle on the wavelength of light can be greatly reduced. Another advantage is that by using thick radiating elements the antenna efficiency can be greatly enhanced, thereby compensating for the reduced efficiency occurring as a consequence of using only a small number of radiating elements in the array.
