Ultrafast all optical switching using pulse trapping in birefringent fibers

Dynamics of solitonlike pulse propagation in birefringent optical fibers.

Integrated Stokes parameters are used to describe solitonlike pulse propagation and its state of polarization in birefringent optical fibers. A qualitative analysis on the Poincare sphere is developed to describe the evolution of the state of polarization of the soliton as a whole. Simple analytic equations describing the pulse evolution are derived in the approximation of the average profile. ...

Artificially disordered birefringent optical fibers.

We develop and experimentally verify a theory of evolution of polarization in artificially-disordered multi-mode optical fibers. Starting with a microscopic model of photo-induced index change, we obtain the first and second order statistics of the dielectric tensor in a Ge-doped fiber, where a volume disorder is intentionally inscribed via UV radiation transmitted through a diffuser. A hybrid ...

Photon pair generation in birefringent optical fibers.

We study both experimentally and theoretically the generation of photon pairs by spontaneous four-wave mixing (SFWM) in standard birefringent optical fibers. The ability to produce a range of two-photon spectral states, from highly correlated (entangled) to completely factorable, by means of cross-polarized birefringent phase matching, is explored. A simple model is developed to predict the spe...

Stationary solitonlike pulses in birefringent optical fibers.

Propagation of solitonlike pulses in birefringent nonlinear fibers has attracted much attention in recent years [1—14]. The equations that describe pulse propagation in these fibers have been derived by Menyuk [1]. These equations are quite complicated and can be solved only in an approximate way for certain specific cases. Two main cases have been studied in depth: high and low birefringent fi...
