Large temporal narrowing of subnanosecond pulses in a low-birefringence optical fiber.
A temporal shortening by a factor higher than 10 of subnanosecond pulses launched into a low-birefringence optical fiber is achieved by polarization filtering at the output. By means of the theoretical approach, in good agreement with experimental measurements, the impact of the nonlinear polarization rotation and of the coherent coupling phenomena is pointed out.
