Abstract:
The invention relates to a supercontinuum light source comprising a microstructured optical fiber and a pump light source. The microstructured optical fiber comprises a core and a cladding region surrounding the core, as well as a first fiber length section, a second fiber length section and an intermediate fiber length section between said first and second fiber length sections. The first fiber length section comprises a core with a first characteristic core diameter. The second fiber length section comprises a core with a second characteristic core diameter, smaller than said first characteristic core diameter, where said second characteristic core diameter is substantially constant along said second fiber length section. The intermediate length section of the optical fiber comprises a core which is tapered from said first characteristic core diameter to said second characteristic core diameter over a tapered length.

Claim (Index 38):
A supercontinuum light source comprising:\n a microstructured optical fiber for generating supercontinuum light at a wavelength \u03bb 1 , said microstructured optical fiber comprising a core region that is capable of guiding light along a longitudinal axis of said optical fiber, and a first cladding region surrounding said core region; and a pump light source arranged to feed light into said core region at an input end of said optical fiber, said light having, a first wavelength, \u03bb 1 , wherein:\n said optical fiber has a length and a longitudinal axis along its length, wherein said optical fiber comprises a first fiber length section, a second fiber length section as well as an intermediate fiber length section between the first and second fiber length sections; \n said first fiber length section has a core region with a first characteristic core diameter W 1 ; \n said second fiber length section has a core region with a second characteristic core diameter W 2  in a cross-section through the microstructured optical fiber perpendicularly to the longitudinal axis, where said second characteristic core diameter W 2  is smaller than said first characteristic core diameter W 1 ; \n said intermediate fiber length section of the optical fiber comprises a core region which is tapered from said first characteristic core diameter W 1  to said second characteristic core diameter W 2  over a tapered length L i ; \n said first fiber length section has normal dispersion at a first wavelength \u03bb 1  and a zero dispersion at a wavelength ZDW 1  where ZDW 1 >about \u03bb 1 +20 nm; and \n said second fiber length section has zero dispersion at a second wavelength ZDW 2 , where said second fiber length section has anomalous dispersion at wavelengths above said second wavelength ZDW 2 .
