Nonlinear optics and nonlinearities in optical fibres

Nonlinear optics and nonlinearities in optical fibres
Nonlinear optics and nonlinearities in optical fibres
Introduction

The phenomena of nonlinear optics are widely varied, both as to the nature of the nonlinear process and the conditions under which they occur. To give some examples; with high power lasers generation of optical harmonic frequencies up to the 20th harmonic have been demonstrated, so that a 1.06µm laser has generated radiation at 53nm[1]; by exploiting the long interaction length and small core diameter available in an optical fibre a stimulated scattering process (Stimulated Brillouin scattering) has been observed with a continuous laser of submilliwatt power output [2]; through the phenomenon of an intensity dependent refractive index in an optical fibre, optical pulses have been compressed temporally to a duration as short as 8fs [3]; by means of nonlinear optical phase-conjugation, lensless imaging can be achieved with submicron resolution [4]. These are just a few examples, which indicate the range of phenomena. The book by Shen gives a comprehensive coverage of the main phenomena [5]. In a short course the subject matter must necessarily cover a limited range and the following topics have been chosen: harmonic generation, frequency mixing, parametric oscillation and amplification; Stimulated Brillouin scattering (SBS); stimulated Raman scattering (SRS); self-focussing and self-phase modulation (SPM); phase-conjugation; nonlinear effects in optical fibres, in particular SBS, SRS and SPM. An aim of the course is to give an elementary discussion of each of the processes, with some typical order of magnitude estimates to indicate efficiency, threshold etc.

Abstract

Introduction

The phenomena of nonlinear optics are widely varied, both as to the nature of the nonlinear process and the conditions under which they occur. To give some examples; with high power lasers generation of optical harmonic frequencies up to the 20th harmonic have been demonstrated, so that a 1.06µm laser has generated radiation at 53nm[1]; by exploiting the long interaction length and small core diameter available in an optical fibre a stimulated scattering process (Stimulated Brillouin scattering) has been observed with a continuous laser of submilliwatt power output [2]; through the phenomenon of an intensity dependent refractive index in an optical fibre, optical pulses have been compressed temporally to a duration as short as 8fs [3]; by means of nonlinear optical phase-conjugation, lensless imaging can be achieved with submicron resolution [4]. These are just a few examples, which indicate the range of phenomena. The book by Shen gives a comprehensive coverage of the main phenomena [5]. In a short course the subject matter must necessarily cover a limited range and the following topics have been chosen: harmonic generation, frequency mixing, parametric oscillation and amplification; Stimulated Brillouin scattering (SBS); stimulated Raman scattering (SRS); self-focussing and self-phase modulation (SPM); phase-conjugation; nonlinear effects in optical fibres, in particular SBS, SRS and SPM. An aim of the course is to give an elementary discussion of each of the processes, with some typical order of magnitude estimates to indicate efficiency, threshold etc.
