Line-by-line spatial Fourier transform of the normalized Faraday rotation image using a logarithmic colour coding. Waveguides are marked by black lines and highlighted with their nominal widths (750 nm to 3 m). Higher-order transverse spin-wave modes are visible in the wider waveguides (2.5 pC m -2 dose) and indicated with numbers n . The modes extend into the adjacent implanted areas.
