Abstract

Six selected optical technologies are evaluated for use in a full-duplex communications link between geostationary satellites. The six systems are based upon the carbon dioxide gas laser, the neodymium-doped yttrium aluminum garnet (Nd:YAG) solid-state laser, the indium gallium arsenide phosphide (InGaAsP) semiconductor diode laser, and the gallium aluminum arsenide (GaAlAs) semiconductor diode laser. The salient features of the various technologies are described and their communications performance analyzed. The antenna diameter requirements for various modulation formats are determined by the analysis. The GaAlAs systems, with their small size, high electrical-to-optical conversion efficiency, direct modulation capability, wavelength selectability, and high reliability are found to he promising technologies for the full-duplex geostationary intersatellite link.
