Stable polarization-dependent self pulsing in a Brillouin amplified spun fiber
… Abstract: A polarization-dependent narrow spectral dip (~1MHz) within the Brillouin
bandwidth of a 900-m elliptical-core spun fiber is associated with stable self pulsing of the
amplified Stokes signal, seeded and pumped by CW lasers. … We believe the self pulsing in
SECF near the “dip” region is the result of nonlinear polarization rotation causing the signal
to experience a higher Brillouin gain than the “dip”, which in turn leads to higher intensity
and more nonlinear polarization rotation. It is a self-reinforcing process that resulted in …
