| 英文摘要 | A tunable monomode light source based on a non-linear four-photons effect and on the interaction resulting from a strong confinement of a pump wave having a first wavelength, injected into a single mode optical fibre of a given length located in a near infrared wavelength spectrum, the light source comprising a generator (SP) for producing said pump wave, optical coupling means (C) for coupling this produced wave to an input face of the optical fibre, characterized in that - the first wavelength (of the pump wave) is situated in the vicinity of the wavelength of zero chromatic dispersion of the optical fibre material, - the cut-off wavelength (lambda c) of the fibre (FO) is selected with respect to the zero dispersion wavelength in such a way that the phase mismatching associated to the mode dispersion properties of the guide structure is zero for discrete wavelengths, - the source comprises a thermostat container in which at least one length portion of said optical fibre of a predetermined length is disposed, and control means allowing to continuously modify the temperature of this container in such a way that the source becomes continuously tunable in said infrared wavelength spectrum. |
