Abstract
Optical fiber sources have experienced a massive growth over the past ten years principally due to the compactness, robustness and good spatial quality of such systems. Fiber sources now cover a large spectrum from visible to near infrared helped on this point by the development of microstructured fibers (MOFs). A particular class of MOFs also called hollow-core photonic crystal fibers (HC-PCFs) offers to get rid of silica's absorption thanks to band gap guidance and therefore to extend transmission range of silica fibers. We propose here two all-fiber architectures based on HCPCFs in view to generate mid infrared wavelengths by amplification of spontaneous Raman scattering (SRS) in gaseous medium. We report on design, fabrication and characterization of two kinds of HC-PCF matching the architecture needs.
