Abstract

The 560 Gb/s ( $20\, {\rm Gb/s} \times 28\, {\rm channels}$ ) DWDM-PON with 16 quadrature amplitude modulation (QAM) orthogonal frequency division multiplexing (OFDM) transmission over 25-km SMF by using the master-to-slave injection-locked weak-resonant-cavity Fabry–Perot laser diode (WRC-FPLD) pair is demonstrated. After master-to-slave injection-locking, the BER of the 16-QAM OFDM data stream under back-to-back and 25-km transmissions can be improved from $3.3 \times 10^{-3}$ to $2.1 \times 10^{-5}$ and from $1.4 \times 10^{-1}$ to $1.2 \times 10^{-3}$ , respectively. With OFDM subcarrier pre-leveling, the BER of 16-QAM OFDM data transmitted by the master-to-slave injection-locked WRC-FPLD over 25-km transmission is further improved from $1.2 \times 10^{-3}$ to $2.1 \times 10^{-4}$ , concurrently enabling the 28 channel transmissions at 20 Gb/s with BER below FEC-limit of $3.8 \times 10^{-3}$ . The back-to-back transmission of pre-leveled 64-QAM OFDM data at 30 Gb/s under is also demonstrated to achieve FEC limited BER at receiving power of –6 dBm by using the main of the master-to-slave injection-locked slave WRC-FPLD. The partially coherent injection-locking of maser-to-slave WRC-FPLD pair is comparable with the coherent DFB injection-locked WRC-FPLD, which is capable of serving as the universal transmitters with competitive performance of a power penalty as low as 0.5 dB between WRCFPLD-to-WRCFPLD and DFB-to-WRCFPLD.
