Hybrid silicon photonic circuits and transceiver for 56Gb/s NRZ 2.2km transmission over single mode fiber

Using hybrid integration of electronics and silicon photonics integrated circuits, we demonstrate the generation and detection of up to 56Gb/s NRZ optical signals over 2km standard single mode fiber at 1310nm wavelength. The link operates error free at 40Gb/s and under KR4 FEC threshold at 56Gb/s.
