“…In addition to affecting these nonlinear processes, polarization trapping can be used to affect the polarization mode delay [4]. Here it was shown that it is possible to control the separation and shape of two polarized solitons by varying the amount of input power.…”

Nonlinear fiber based devices and in particular multiple wavelength nonlinear fiber devices are reviewed. A number of important devices can be fabricated using various lengths of fiber in combination with the appropriate input signals and pumps of sufficient power. The low loss fiber provides a unique medium whereby these important nonlinear processes can occur. These processes include among others Brillouin scattering, Raman scattering, parametric amplification, wavelength conversation, self phase modulation, and four wave mixing. Possible applications for these processes include high bit rate dynamic dispersion compensation, 2R regeneration, the continuum generation and nonlinear polarization dynamics.

“…8 c, which means that the two polarization components of the vector optical soliton propagate with nearly matched, ultraslow propagating velocities. As we have stressed, different from the passive media such as optical fibers [2,3,4,5,6,7,8,9,10] the parameters of our present EIT medium can be actively manipulated. Consequently the coefficients of Eq.…”

“…In recent years, considerable attention has been paid to the temporal [1,2,3,4,5,6] and spatial [7,8,9, 10] vector optical solitons in various nonlinear systems. Due to their remarkable property, vector optical solitons have promising applications for the design of new types of all-optical switches and logic gates [12].Up to now, most vector optical solitons are produced in passive media such as optical fibers [2,3,4,5,6,7,8,9,10], in which far-off resonance excitation schemes are employed in order to avoid unmanageable optical attenuation and distortion. However, due to the lack of distinctive energy levels, the nonlinear effect in such passive media is very weak, and hence to form vector solitons a very high input light-power is required.…”

We propose a scheme to generate temporal vector optical solitons in a lifetime broadened fivestate atomic medium via electromagnetically induced transparency. We show that this scheme, which is fundamentally different from the passive one by using optical fibers, is capable of achieving distortion-free vector optical solitons with ultraslow propagating velocity under very weak drive conditions. We demonstrate both analytically and numerically that it is easy to realize Manakov temporal vector solitons by actively manipulating the dispersion and self-and cross-phase modulation effects of the system. PACS numbers: 42.65.Tg, 42.50.GyThe vector nature of light propagating in a nonlinear medium has led to the discovery of a novel class of solitons, i. e. vector optical solitons, which are the solutions of two coupled nonlinear Schrödinger (NLS) equations describing the envelope evolution of two polarization components of an electromagnetic field. In recent years, considerable attention has been paid to the temporal [1,2,3,4,5,6] and spatial [7,8,9, 10] vector optical solitons in various nonlinear systems. Due to their remarkable property, vector optical solitons have promising applications for the design of new types of all-optical switches and logic gates [12].Up to now, most vector optical solitons are produced in passive media such as optical fibers [2,3,4,5,6,7,8,9,10], in which far-off resonance excitation schemes are employed in order to avoid unmanageable optical attenuation and distortion. However, due to the lack of distinctive energy levels, the nonlinear effect in such passive media is very weak, and hence to form vector solitons a very high input light-power is required. In addition, the lack of distinctive energy levels and transition selection rules also makes an active control very difficult. In particular, it is hard to realize Manakov[11] temporal vector optical solitons in optical fibers because the ratio between self-phase modulation (SPM) and cross-phase modulation (CPM) is not unity and there is also detrimental energy exchange between two polarization components due to the existence of four-wave mixing effect. Manakov vector optical solitons are of great interest, not only because the coupled NLS equations describing them have beautiful mathematical properties but also such solitons may be used to realize all-optical computing [13]. Different from spatial Manakov vector optical solitons, which have been observed more than ten years ago [8], temporal Manakov vector optical solitons have not been realized in experiment up to now.In this Letter, we propose a scheme to generate temporal vector optical solitons in a coherent five-level atomic system via electromagnetically induced transparency (EIT). This resonant EIT medium has been recently used to realize polarization qubit phase gate [14] and reversible memory devices for photon-polarization qubit [15]. We show that two continuous-wave (CW) control laser fields established prior to the injection of a pulsed probe field induce a quantum interferen...
