Paper Abstract

A laboratory model of a bidirectional semiconductor laser data link package with acquisition and tracking capability was realized and tested. The system consists of two independent transceivers spaced at a distance of typically 20m. The transceivers are built around a GaAlAs-laser (X=0.85μm) and a Ge-photodiode in one case and an InGaAsP-laser (X=1.3μm) and Si-detectors in the second case. The 0.85pm beam carries a 10Mbit/s data stream, while the 1.3μm beam transmits a low-data-rate signal at 160kbit/s. One transceiver is mounted on a test jig which permits transverse movement over an area of 1m x lm. At a transmitted optical power level of 0.5mW reliable data transmission (BER<10-9), pointing, acquisition (Tacquisition<10s), and tracking (NEAz2Oprad) were demonstrated.
