Nonlinear Fiber Optics

Abstract: Nonlinear fiber optics concerns with the nonlinear optical phenomena occurring inside optical fibers. Although the field ofnonlinear optics traces its beginning to 1961, when a ruby laser was first used to generate the second-harmonic radiation inside a crystal [1], the use ofoptical fibers as a nonlinear medium became feasible only after 1970 when fiber losses were reduced to below 20 dB/km [2]. Stimulated Raman and Brillouin scatterings in single-mode fibers were studied as early as 1972 [3] and were soon followed by the study of other nonlinear effects such as self- and crossphase modulation and four-wave mixing [4]. By 1989, the field ofnonlinear fiber optics has advanced enough that a whole book was devoted to it [5]. This book or its second edition has been translated into Chinese, Japanese, and Russian languages, attesting to the worldwide activity in the field of nonlinear fiber optics.

Attosecond Metrology

Abstract: Attosecond metrology also exploits the sub-cycle time-dependent field of the laser to provide the shear needed to measure attosecond optical or electron pulses. Always the shear is applied to electrons because they respond easily to electric fields. Attosecond pulses can be measured in the nonlinear medium while they are being generated or they can be measured more conventionally, in a separate nonlinear medium. In this case, attosecond optical pulses transfer their amplitude and phase information to photoelectrons which are measured in their place. As in femtosecond science, measuring an ultrashort pulse and measuring an ultrafast dynamics excited by an attosecond pulse is similar. This paper describe the methods of attosecond metrology.

Light waves at the boundary of nonlinear media

Abstract: Solutions to Maxwell's equations in nonlinear dielectrics are presented which satisfy the boundary conditions at a plane interface between a linear and nonlinear medium. Harmonic waves emanate from the boundary. Generalizations of the well-known laws of reflection and refraction give the direction of the boundary harmonic waves. Their intensity and polarization conditions are described by generalizations of the Fresnel formulas. The equivalent Brewster angle for harmonic waves is derived. The various conditions for total reflection and transmission of boundary harmonics are discussed. The solution of the nonlinear plane parallel slab is presented which describes the harmonic generation in experimental situations. An integral equation formulation for wave propagation in nonlinear media is sketched. Implications of the nonlinear boundary theory for experimental systems and devices are pointed out.
