A Silicon Photonics Technology for 400 Gbit/s Applications

A Silicon photonics platform operating at 100 Gbit/s (53Gbaud-PAM4) per lane is demonstrated. Integration of 60 GHz High-Speed Photodiode and efficient High-Speed Phase Modulator into a 400G-DR4 3D test chip is shown. Extension towards 400G-FR4 is addressed by the introduction of a SiN layer allowing wideband fiber to the chip optical coupling and polarization management.
