Transient stimulated Brillouin scattering dynamics in polarization maintaining optical fiber

摘要

Summary form only given. We experimentally investigate SBS in polarization-maintaining (PM) fiber with square optical pulses having a duration short compared to the fiber transit time, and show that just above threshold, SBS is generated over the entire length of the fiber. We also present measurements of the SBS threshold for pulse durations short compared to the SBS phonon lifetime (/spl sim/16 ns) and show detailed measurements of the pulse distortion on the pulse transmitted through the fiber.
