We present a setup able to generate and detect single
photons in optical fibers using the stimulated four-wave
mixing (FWM) process. The results show an accurate generation
of single photons at four different linear states of polarization
(SOPs), with angles 0, 45, 90 and -45 degrees. The detection
was performed in back-to-back configuration and after
transmission over an optical fiber with a length up to 10 m.
