(a) Grating coupler for coupling between photonic wire waveguide and fibre. (b) Oblique view of a holographic lens connected to silicon waveguides. The optical fibre illuminates the holographic lens from a position normal to the surface. The core of the fibre is shown by the dashed lines. Figure (a) is taken from [17, 18]. Figure (b) is taken from [22].
