Short wavelength generation using sub-micrometre diameter optical fibres
Short wavelength generation using sub-micrometre diameter optical fibres
Light generation at short wavelengths, particularly in the UV spectral range, has numerous potential applications, such as biomedical, lithography and undersea communications. To date, this has been achieved using excimer lasers like KrF or XeCl, expensive diodes or near-IR lasers with nonlinear crystals, which suffer from poor beam shapes, relatively complicated optics and relatively low power. Recently, intermodal third harmonic generation in sub-wavelength optical fibres has been proposed to generate light at short wavelengths from near IR laser sources. However, conversion efficiencies have been limited to 10-3 because of the intrinsic surface waves frozen in all amorphous materials during the glass-making process. Here, light at short wavelengths have been generated in optical fibres using the intermodal four wave mixing (FWM) in tapered optical fibres with sub-micrometer diameter.

Abstract
Light generation at short wavelengths, particularly in the UV spectral range, has numerous potential applications, such as biomedical, lithography and undersea communications. To date, this has been achieved using excimer lasers like KrF or XeCl, expensive diodes or near-IR lasers with nonlinear crystals, which suffer from poor beam shapes, relatively complicated optics and relatively low power. Recently, intermodal third harmonic generation in sub-wavelength optical fibres has been proposed to generate light at short wavelengths from near IR laser sources. However, conversion efficiencies have been limited to 10-3 because of the intrinsic surface waves frozen in all amorphous materials during the glass-making process. Here, light at short wavelengths have been generated in optical fibres using the intermodal four wave mixing (FWM) in tapered optical fibres with sub-micrometer diameter.
