EVALUATION OF AN OPTICAL INTERSATELLITE LINK USING A HIGH POWER LASER DIODE

摘要

In an optical Intersatellite Link (ISL), high optical power is required, because the beam needs to propagate over the considerable distances between satellites. The objective of this study is to analyze optical ISL using a high power LD, which has multiple peaks in its radiation spectrum. We demonstrate that LD output power of 1 W would enable a data rate of 1.1 Gbps via a GEO-LEO link, and 9.7 Mbps via an Earth-moon link when BER is 10-s. Output power of 9.5 W would be necessary to communicate at a data rate of 600 bps via an Earth-Mars link.
