96 Gbit/s PAM-4 Generation using an Electro-Optic Polymer Modulator with High Thermal Stability

The thermal stability of electro-optic polymer modulators is improved using a common ridge and hybrid silicon-to-polymer waveguide-structure. It reveals excellent thermal resistance at 105°C for ∼2, 000 hours and generates 56Gbit/s OOK and 96Gbit/s PAM-4 successfully.
