We report, to the best of our knowledge, the first demonstration of 320 Gb/s all-optical clock recovery and all-optical time de-multiplexing after 51 km transmission by exploiting single-quantum dash mode-locked laser diode (QD-MLLD). Based on injection locking of the QD-MLLD, the 40 GHz synchronized optical clock pulses were recovered from the 320 Gb/s with a pulse width of 1.9 ps and timing jitter of 135 fs, which allowed directly time de-multiplexing of 320-40 Gb/s without additional complex optoelectronic circuitry. The 320-40 Gb/s all-optical de-multiplexing was achieved with averaging a power penalty of 4.5 dB at BER of 1E-6.
据我们所知，我们首次展示了通过利用单量子 Dash 锁模激光二极管 (QD-MLLD) 在 51km 传输后实现 320Gb/s 的全光时钟恢复和全光时分复用。基于 QD-MLLD 的注入锁定，从 320Gb/s 恢复出 40GHz 的同步光时钟脉冲，其脉冲宽度为 1.9ps，定时抖动为 135fs，这允许直接对 320-40Gb/s 进行时分复用，而无需额外的复杂光电电路。在误码率为 1E-6 时，通过平均功率代价为 4.5dB，实现了 320-40Gb/s 的全光解复用。
