Abstract :
A polymethylmethacrylate
(PMMA) microstructured polymer optical fiber
(mPOF) is fabricated and characterized. Using
the cut-back technique the fiber loss is
measured which is higher than the step-index
silica fibers. Through a novel experimental
scheme, the backward Stokes spectrum of the
fabricated mPOF is recorded over a range
exceeding 3000 (cm)^(-1)
during the cut-back
method and compared with that of step-index
silica fiber. Especially, the gain coefficient of the
Raman peak at 2950 (cm)^(-1)
is directly measured,
that is without comparing with other known
material. The results show a very good
agreement with those obtained through other
experimental schemes.
