“…With the growing availability of optical fiber building blocks compatible with the mid-IR such as optical fibers, fiber tapers, OFCs, optical fiber saturable absorbers [85], and certainly many others to come, it is expected that all-fiber devices and all-fiber light sources will quickly develop. Just recently, the first all-fiber chalcogenide ring laser has been demonstrated [86]. It consists of a combination of an As 2 S 3 optical fiber for nonlinear amplification and of an As 2 Se 3 OFC to close the resonant ring cavity, inject pump power, and extract laser power.…”

Alloys of sulphur, selenium and tellurium, often referred to as chalcogenide semiconductors offer a highly versatile, compositionally-controllable material platform for a variety of passive and active photonic applications. They are optically nonlinear, photoconductive materials with wide transmission windows that present various high- and low-index dielectric, low-epsilon and plasmonic properties across ultra-violet, visible and infrared frequencies, in addition to an ultra-fast, non-volatile, electrically-/optically-induced switching capability between phase states with markedly different electromagnetic properties. This roadmap collection presents an in-depth account of the critical role that chalcogenide semiconductors play within various traditional and emerging photonic technology platforms. The potential of this field going forward is demonstrated by presenting context and outlook on selected socioeconomically important research streams utilizing chalcogenide semiconductors. To this end, this roadmap encompasses selected topics that range from systematic design of material properties and switching kinetics to device level nanostructuring and integration within various photonic system architectures.

For the first time, a 2×2 optical fiber coupler based on indium fluoride optical fibers is designed via coupled mode theory, fabricated via fused biconical tapering technique, and characterized in the mid-infrared spectral range. A conventional glass processing system, Vytran ® GPX-2400, is employed for the 2×2 optical fiber coupler fabrication, overcoming the main limitation related to the narrow temperature range for indium fluoride optical fiber processing. Moreover, the fabricated device exhibits negligible surface crystallizations. The experimental results are in optimum agreement with the simulations, demonstrating that reproducible manufacturing of low-loss fused optical fiber components for the mid-infrared spectral range is possible. In particular, the fabricated 2×2 optical fiber coupler is characterized by a measured coupling ratio 𝑪𝑹 = 𝟕𝟐. 𝟐: 𝟐𝟕. 𝟖 at the wavelength 𝝀 = 𝟑. 𝟑𝟒 𝝁𝒎, with low excess loss 𝑬 𝑳 = 𝟎. 𝟖𝟖 𝒅𝑩.

“…In contrast to silica, fluoride and chalcogenide fibers are transparent to mid-infrared light, up to 5 µm for ZBLAN and 12 µm for As 2 S e 3 fibers. Chalcogenide OFCs have already been demonstrated in the form of singlemode OFCs [1][2][3], nonlinear OFCs [4], and also served in the fabrication of laser cavities [5,6], but remain an emerging technology that needs refinement before commercialization. In contrast, fluoride glass OFCs have yet to be developed, mainly due to crystallization that spontaneously occurs close to the softening temperature [7].…”
