This proposal addresses a solution to a critical problem for space communication- that of high-power optical wavelength division multiplexing for point to multipoint space communications. The target is to ultimately combine 25 channels at 40W optical per channel for a 1kW space-based unit. In order to establish a solution suitable for operation in space, several approaches will be explored. These include a Mach-Zehnder based multiplexer, an in-fibre coupler based Bragg grating multiplexer, and a multifibre coupler combiner. To fully understand the issues that need to be resolved, a 3D printed scaled up cylindrical dielectric model operating with printed Bragg gratings operating at THz frequencies will be studied. The results of this evaluation will be used to fabricate FS written in coupler gratings. Attention will be focused on insertion loss, efficiency and footprint, as required for space applications.

该方案解决了空间通信中的一个关键问题--点对多点空间通信的高功率光波分复用。目标是最终组合25个通道，每个通道40W光纤，形成一个1kW的天基单元。为了建立一种适合在太空中运行的解决方案，将探索几种方法。其中包括基于Mach-Zehnder的复用器、基于光纤耦合器的布拉格光栅复用器和多光纤耦合器组合器。为了充分理解需要解决的问题，我们将研究以太赫兹频率工作的打印布拉格光栅工作的3D打印放大圆柱介质模型。评估的结果将被用于制作写入到耦合光栅中的FS。将重点关注空间应用所需的插入损失、效率和占地面积。
