Patent number: 6850712Abstract: A technique for suppressing stimulated Brillouin scattering SBS along an optical fiber signal path utilizes polarization modulation at the transmitter to split the launched power into orthogonal polarization states. By reducing the power along each polarization, SBS will be reduced. Linewidth broadening of the optical source is achieved by introducing: (1) a incoherence between the polarization states (using a time delay along the signal path of one polarization state); and (2) a frequency shift between the polarization states (using an acousto-optic modulator along the signal path of the remaining polarization state).Type: GrantFiled: May 31, 2000Date of Patent: February 1, 2005Assignee: Lucent Technologies Inc.Inventors: Jean-Marc Pierre Delavaux, Aydin Yeniay
