400 Gbps/$\lambda$ O-Band Coherent Link Using SiP TX and RX PICs With Heterogeneously Integrated Lasers and SOAs
We report a net 400 Gbps/<inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"><tex-math notation="LaTeX">$\lambda$</tex-math></inline-formula> O-band, dual-polarization, intradyne coherent link using silicon photonic (SiP) transmitter and receiver photonic integrated circuits (PIC) with heterogeneously integrated lasers and semiconductor optical amplifiers (SOA). Operation below the 15.3% overhead 2×10<inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"><tex-math notation="LaTeX">$^{-2}$</tex-math></inline-formula> open forward error correction (O-FEC) threshold was achieved for 60 Gbaud 16QAM over 2 km and 100 Gbaud QPSK over 10 km without external optical amplification. These results demonstrate the potential for implementing SiP PICs with integrated lasers and SOAs in future short-reach coherent links.
