Paper Abstract

Remote distance sensing using an all-fiber Mach-Zehnder interferometer has been demonstrated. The system employed a frequency modulated, coupled-cavity semiconductor laser with constant output power. Accuracy of 0.5% was obtained in absolute distance measurements, and relative displacements on the order of 0.1 mm were detected. The same interferometer was also used to characterize the tuning properties of semiconductor lasers.
