Stimulated Raman Scattering (SRS) is a nonlinear physical effect of essential importance for the new developing generation of fibre lasers and amplifiers. Its main limitation is that it requires, in normal optical fibres, fairly high input powers and long interaction lengths. The advent of highly nonlinear photonic crystal fibres (PCFs) may change that and permit a wider use of SRS for telecommunications applications in which the size of the system is important. The proposed collaboration will be devoted to a study of SRS in these fibres. Because the light in PCF can be tightly guided in a narrow core, one can take advantage of a stronger nonlinear optical response. High optical densities in such fibres have been shown to generate a wealth of nonlinear effects, the physics of which we intend to study in details. SRS and the generation of supercontinuum light are two such effects. We plan to study these effects for a variety of optical inputs, from CW to ultrashort pulses and look at their time evolution. Raman being an interaction between light and molecular vibrations or (optical) phonons, the proposed study will hopefully also provide information about phonons in an inhomogeneous (or two-phase) medium.
