Abstract

This work investigates optically amplified bidirectional transmission with a quantum-dot semiconductor optical amplifier for next-generation 100G passive optical networks. We experimentally demonstrate 100/150 Gbit/s uplink/downlink bidirectional PAM-4 transmissions employing a quantum-dot semiconductor optical amplifier in the remote node of an optical access network. After 20 km optically amplified transmission, we attain the uplink/downlink power budgets of 32.3 dB/29 dB at the HD-LDPC bit error ratio decision threshold of

$10^{\mathrm {-2}}$

with an overhead of 15.5%, satisfying the power budget requirements of a legacy passive optical network with net (gross) achievable uplink/downlink data rates of 84.4/126.7 (100/150) Gbit/s, respectively.

面向未来无源光网络的QD-SOA双向100G/150G放大传输

本文研究了下一代100G无源光网络中量子点半导体光放大器的光放大双向传输。利用量子点半导体光放大器在光接入网的远端节点上实验演示了100/150 Gbit/s的上行/下行双向PAM-4传输。经过20公里的光放大传输，在HD-LDPC误码率决策阈值为$10^{\ mathm{-2}}$时，我们获得了32.3 dB/29 dB的上行/下行功率预算，开销为15.5%，满足了传统无源光网络的功率预算要求，净（总）可实现的上行/下行数据速率分别为84.4/126.7 (100/150)Gbit/s。

期刊介绍： IEEE Photonics Technology Letters addresses all aspects of the IEEE Photonics Society Constitutional Field of Interest with emphasis on photonic/lightwave components and applications, laser physics and systems and laser/electro-optics technology. Examples of subject areas for the above areas of concentration are integrated optic and optoelectronic devices, high-power laser arrays (e.g. diode, CO2), free electron lasers, solid, state lasers, laser materials'' interactions and femtosecond laser techniques. The letters journal publishes engineering, applied physics and physics oriented papers. Emphasis is on rapid publication of timely manuscripts. A goal is to provide a focal point of quality engineering-oriented papers in the electro-optics field not found in other rapid-publication journals.
