Paper Abstract

The observation of Second Harmonic Generation (SHG), in centrosymmetric silica optical fibres stimulated great theoretical and experimental interest, in the study of this phenomenon with potential applications. SHG could be observed mainly in Ge doped or Ge-P doped silica fibres, and it has been established that some doping is essential for SHG in optical fibres. Several physical models have been proposed to explain this phenomenon, and almost all the models explain the origin of this x(2) effect through the x(3) effect in silica fibres. In this paper, we present a coupled mode analysis to study SHG in optical fibres. Both ‘seeded’ and ‘unseeded’ SHG have been analysed, taking into consideration the transverse modal distribution in the fibre. Details on our experimental efforts to observe SHG in Ge doped optical fibres are also presented.
