New Trends in Amplifiers and Sources via Chalcogenide Photonic Crystal Fibers

Abstract

Rare-earth-doped chalcogenide glass fiber lasers and amplifiers have great applicative potential in many fields since they are key elements in the near and medium-infrared (mid-IR) wavelength range. In this paper, a review, even if not exhaustive, on amplification and lasing obtained by employing rare-earth-doped chalcogenide photonic crystal fibers is reported. Materials, devices, and feasible applications in the mid-IR are briefly mentioned.

Advances on Optical Fiber Sensors

“…FBGs allow fine control of fiber laser cavity by finely tuning their distributed reflectivity. This potential is strategic in the optimal design of both conventional and MOF fiber lasers [38][39][40][41][42][43][44][45] and therefore in the design of DBR and DFB laser sensors.…”
