Abstract

This paper discusses a new concept of free-space optical (FSO) communication terminals, characterized as the mutual tracking of near field Gaussian beams and the direct single mode fiber coupling to achieve Tera-bit/seconds (Tbps) class FSO link in short range outdoor environments. It first shows the required optical configurations including beacon transmitters, tracking sensors and fast steering mirrors to construct the mutual tracking system and then discusses their capabilities and performance for this specific near field operation in which conventional tracking system is not enough to assure stable and reliable link performance. It also presents one of the simplest realizations of the new FSO terminals and their test results.
