Abstract

In this paper, we present a cost-effective double-clad fiber (DCF) coupled laser communication terminal for short-range inter-satellite optical wireless communication systems. Taking advantage of the robust coupling efficiency provided by DCF, a maximum-minimum received optical power fluctuation of 5.82 dB is achieved under the condition of residual misalignment through a 4.1 km free-space link, and a real-time bidirectional digital video transmission has been successfully demonstrated. Compared with previous laser communication terminals, by saving the pre-EDFA, our design reduces the power consumption of the communication part by >18.5 % and improves the overall energy efficiency by >3 %. Consequently, the proposed DCF-coupled laser communication terminal satisfies the target scenario and shows its potential for future application.

用于近程星间光无线通信系统的高性价比双包层光纤耦合激光通信终端的论证

本文提出了一种低成本的双包层光纤（DCF）耦合激光通信终端，用于近距离星间光无线通信系统。利用DCF提供的鲁棒耦合效率，通过4.1 km的自由空间链路，在剩余不对准条件下实现了5.82 dB的最大最小接收光功率波动，并成功实现了实时双向数字视频传输。与以往的激光通信终端相比，通过节省前置edfa，我们的设计使通信部分的功耗降低了18.5%，整体能效提高了3%。因此，所提出的dcf耦合激光通信终端满足了目标场景，显示了其未来应用的潜力。

期刊介绍： Innovations in optical fiber technology are revolutionizing world communications. Newly developed fiber amplifiers allow for direct transmission of high-speed signals over transcontinental distances without the need for electronic regeneration. Optical fibers find new applications in data processing. The impact of fiber materials, devices, and systems on communications in the coming decades will create an abundance of primary literature and the need for up-to-date reviews. Optical Fiber Technology: Materials, Devices, and Systems is a new cutting-edge journal designed to fill a need in this rapidly evolving field for speedy publication of regular length papers. Both theoretical and experimental papers on fiber materials, devices, and system performance evaluation and measurements are eligible, with emphasis on practical applications.
