Abstract
AbstractThe combination of the unique optical properties of chalcogenide glasses, in terms of infrared transmission and optical non-linearity, with the original guiding properties of microstructured optical fibers leads to a new category of fibers with promising applications in mid-infrared optics. The recent developments on chalcogenide microstructured optical fibers are exposed and discussed with regards to mid-IR guiding, infrared light transport and delivery, generation of new infrared sources, and infrared spectroscopy.
Highlights
In recent years, a growing interest has settled for optical materials and devices for the mid infrared region, which corresponds to the 2–20 μm electromagnetic spectral range
Stimulated Brillouin scattering (SBS) in optical fibers are important nonlinear interactions that can be exploited to obtain wavelength conversion and highly coherent lasers, in chalcogenide fibers where the Brillouin gain can reach more than 120 times the gain measured in a silica fiber
The results, obtained for similar lengths of fiber interacting with acetone, show that the microstructured exposed-core (MEC) fiber is significantly more sensitive than the single-index fiber
Summary
A growing interest has settled for optical materials and devices for the mid infrared (mid-IR) region, which corresponds to the 2–20 μm electromagnetic spectral range. For wavelengths longer than 5 μm, transmission of light can be only obtained with hollow core fibers [2], crystalline silver halide fibers [3,4] and chalcogenide glass fibers. This geometry permits to obtain a single-mode polarizationmaintaining MOF covering the mid-IR region from 3 to 8·5 μm.
