Observation of polarization-locked vector solitions in optical fiber



B C. Collins, N N. Akhmediev, J M. Soto-Crespo, K Bergman, W H. Knox


We observe the formation of polarization-locked vector solitons in a modelocked fiber laser. Temperal vector solitons contain components along both principal axes of the birefringent laser cavity. The relative phase of the two components is locked to a value of +- &/2, despite the different phase velocities due to linear birefringence, resulting in a fixed elliptical polarization state. The value of +- &/2 and component magnitudes agree with a simple theoretical analysis of effect of the Kerr nonlinearity in the optical fiber. These fragile phase-locked vector solitons have been the subject of much theoretical conjecture, but have previously eluded experimental observation.
