TLDR
In this paper, a highly nonlinear Holey fiber for making a mid-infrared light source at 4.36 µm was designed and a solid-core chalcogenide-based index-guided Holey microstructured optical fiber with circular air holes was exploited to numerically demonstrate wavelength translation via four-wave mixing.Abstract:
We report the design of a highly nonlinear holey fiber for making a mid-infrared light source at 4.36 μm. A solid-core chalcogenide-based index-guided holey microstructured optical fiber with circular air holes has been exploited to numerically demonstrate wavelength translation via four-wave mixing. We employ a thulium-doped fiber laser as the pump with a power of 5 W. Our simulations indicate that a maximum parametric gain of 20.5 dB with a bandwidth of 16 nm is achievable in this designed fiber, resulting in a power conversion efficiency of more than 17.6%.read more

Tunable parametric amplifier for mid-IR application based on highly nonlinear chalcogenide material
TL;DR: In this paper, a novel dispersion controlling technique towards attaining tunable parametric amplification based on highly nonlinear photonic crystal fibers has been investigated, where selective infiltration of the liquid into the air-holes leads to alter the zero dispersion wavelength towards a broader parametric gain in the mid-IR spectrum by only changing the temperature of the system externally.
