Abstract
A scheme for high speed clock and data recovery using an electroabsorption modulated laser and a semiconductor optical amplifiers arranged in an optical-electrical-optical (OEO) loop has been demonstrated. By injecting the 80Gb/s optical data into the OEO ring, the 10GHz clock tone is traced and amplified in the loop. A 10GHz electrical clock and, a 10 GHz optical clock are recovered simultaneously.
