First Experimental Observation of Polarization Locked Temporal Vector Solitons
We experimentally observe polarization locked temporal vector solitons, i.e. solitons that preserve their polarization despite a birefringent environment, in a passively mode-locked fiber laser. The two intracavity orthogonal polarization modes of a 420 fs soliton pulse phase lock when the differential nonlinear phase shift arising from their unequal intensities compensates for the linear cavity birefringence. The stabilization mechanism involving the nonlinear coherent energy coupling between components is described.
