“…Moreover, integrated intradyne coherent receiver which implements 90 degrees optical hybrid and balanced photo detectors has already been demonstrated for space environmental test on the ground [23]. Commercial Off-The Shelf (COTS)-based FPGA is also applied as a high-speed electronics device for DSP circuit [24] and will be demonstrated on orbit [25]. The COTS-based FPGA enables high-speed processing of BPSK signal which is based on HDR method.…”

JAXA and NICT have started the collaborative research for cislunar optical communications. NICT is responsible for research and development some of key technologies for cislunar optical communication systems utilizing GEO relay satellite. NICT has especially focused on research and development of a large-aperture optical antenna, high-sensitivity optical communication system applying adaptive optics and HDR method, which is based on binary phase shift keying scheme, onboard the GEO relay satellite. In this paper, we will present the overview of collaborative research and key technologies for cislunar optical communication systems. We will also describe the current status of our research and development activities.
