Abstract :
In this paper, a coarse photopolymer grating-based WDM device is proposed and developed to work for a simple point-to-point data transfer between two satellites. The four-channel CWDM device reported herein provides two data streams at 0.83 μm and 1.55 μm, an inter-satellite tracking channel at 1.06 μm, and an intra-satellite communication channel at 1.34 μm. This device works properly in the current optical satellite medium bit rate system based on 0.8 μm technology and its performance can also be maintained in the future high bit rate system using 1.5 μm technology.
