Paper Abstract

Stimulated Brillouin scattering (SBS) in plastic optical fibers (POFs) is observed, for the first time to the best of our knowledge, using pump-probe technique without lock-in detection, and the dependences of the Brillouin gain spectrum on POF length, pump power, and probe power are fully investigated. An optimal POF length exists for SBS observation, because POFs have relatively high propagation loss of 250 dB/km at 1.55 μm; it is found to be 3.8 m when 21.1-dBm pump and 22.2-dBm probe waves are used. As the probe and pump powers grow higher, the Stokes power is also increased but nonlinearly, which indicates that the Brillouin signal observed with this technique can be directly applied to the implementation of POF-based Brillouin optical time-domain analysis systems.
