Beschreibung
Zusammenfassung:	There is described an RF waveguide array. The array comprises a substrate comprising a plurality of optical waveguides, each waveguide being elongate in a first direction. An electrical RF transmission line array is located on a face of the substrate and comprises a plurality of signal electrodes and a plurality of ground electrodes, each electrode extending in the first direction. Each signal electrode is positioned to provide a signal to two respective waveguides. The ground electrodes include at least one intermediate ground electrode positioned between each pair of signal electrodes. Each intermediate ground electrode includes a portion extending into the substrate.
