CMOS compatible SOI photonic integrated circuits (PICs) offer a low cost and promising solution to future short reach optical links operating beyond 100 Gb / s. A key building block in these optical links is the external optical modulator. Amongst, the PIC geometries for external modulators are those based upon ring resonators and Mach-Zehnder interferometers (MZI) where whilst the latter have been reported with increased thermal stability and fabrication tolerances, the former have demonstrated lower loss and lower driving voltages leading to a more energy efficient approach. Multi-segmented electrode structure based PAM optical modulator can potentially replace the analog digital-to-analog circuits (DACs) which are commonly used to achieve the multilevel electrical driving signal. Accordingly, it would be beneficial to combine the benefits of ring resonators to provide PAM-N modulators. It would be further beneficial for such PAM-N ring resonator modulators to exploit multi-segmented electrode structures to remove the requirements for high speed DACs.
