Optical pulse shaping by doublet Brillouin gain lines in a single-mode tellurite fiber

Abstract

Tunable all-optical fine control of pulse width via doublet Brillouin gain lines was demonstrated in a short 204-m-long nonlinear single-mode tellurite fiber. Gaussian pulse shaping with a compression ratio ranging from 1.17-0.27 was achieved after the input square pulse was amplified by the modulated Brillouin gain in this tellurite fiber.
