Query: Design of an efficient Mid-IR light source using As2S3 based highly
  nonlinear microstructured optical fibers   We report on the design of a highly-nonlinear specialty fiber as a
mid-infrared light source at 4.3 {\mu}m. A meter length of the designed
solid-core chalcogenide based index-guided microstructured optical fiber (MOF)
with circular air holes has been exploited to translate wavelength via four
wave mixing using a thulium-doped fiber laser as the pump with a relatively low
peak power of 5 W. A peak gain value of around 37 dB with full width at half
maxima (FWHM) less than 3 nm is achieved.
