Bistable holes in nonlinear optical fibers

Optics Letters, 1989
Bistable dark solitary-wave solutions (bistable holes) to the generalized nonlinear Schrödinger equation are shown to exist in the normal dispersion regime for nonlinearities that are Kerr-like at low intensities, rise sufficiently rapidly at intermediate intensities, and become Kerr-like again or approach a constant value at large intensities.

Nonlinear Optical Interactions in Optical Fibers

Journal of Nonlinear Optical Physics & Materials, 1998
We report on our research program aimed at clarifying the physical processes leading to the nonlinear optical response of silica optical fibers and at studying the implications of optical nonlinearities on optical pulse propagation and optical switching devices.

Optical Fibers for Nonlinear Optics.

1986
Abstract : The main objective of this contract has been to find methods of fabricating single-crystal nonlinear optical fibers. Successful techniques were to be utilized to make crystal fibers useful for nonlinear optical devices, particularly devices exploiting second order optical nonlinearities.

Nonlinear Optics and Optical Fibers

2000
In the various discussions concerning the propagation of light in material media such as silica optical fibers, in the previous chapters we have been dealing with linear processes. By this we mean that a light beam of a certain optical frequency which enters a given medium will leave the medium with the same frequency, although the amplitude and phase ...

Optical wave breaking of pulses in nonlinear optical fibers

Optics Letters, 1985
A new effect appears in femtosecond optical pulse compression, using single-mode fibers, that we describe as optical wave breaking. In the fiber, frequency-shifted light in the leading and trailing edges of a pulse overtakes unshifted light in the pulse tails.

Hamiltonian description of nonlinear propagation in optical fibers

Physical Review A, 1988
Nonlinear propagation in single-mode and multimode fibers in the presence of the optical Kerr effect is described in terms of a number of parameters (four for each propagating mode) which can be interpreted as conjugate variables of a suitable Hamiltonian system.

Investigation of Optical Fibers for Nonlinear Optics.

1983
Abstract : The principal objective of this research program is to develop single-crystal (SC) fibers for use in nonliner optical devices. This encompasses measurement of physical and chemical properties of several candidate materials, fabrication of SC fibers, and investigation of nonlinear optical applications.
