300 GHz OOK Transmitter Integrated in Advanced Silicon Photonics Technology and Achieving 20 Gb/s

摘要

In this paper, a 300 GHz 20 Gb/s On-Off Keying (OOK) transmitter is demonstrated in advanced Silicon-Photonics process. An integrated Silicon-Germanium photodiode is optically excited by the beatnote of two tunable lasers in order to up-convert data signals from baseband to 300 GHz. Using a receiver based on direct detection in III-V Schottky diode, measured Bit Error Rates (BER) below the value of 1.10^{-9were achieved at 20 Gb/s in real time, and a real-time BER below the Forward Error Correction (FEC) was successfully measured at 25 Gb/s.}
