Abstract
“Mid-InfraRed (MIR) fiber photonics” is an important emerging technology worldwide. The MIR spectral region (3 μm wavelength) offers great potential for molecular sensing systems that will translate across sectors from security to healthcare; MIR laser cutting and welding at new wavelengths of soft materials will include medical surgery of human tissue. Chalcogenide glasses present windows within the 1–20 μm region and chalcogenide glass optical fibers are suitable for routing MIR light and as active laser sources. Chapter 8 is a critical review of the last 10 years’ research on lanthanide-ion doped chalcogenide bulk glasses and fibers up to, and including, the advent of bulk glass lasing, at >5 μm, in 2020 and 2021. Photoluminescent behavior is critically analyzed, including absorption and emission cross-sections, lifetimes, branching ratios of praseodymium, dysprosium, terbium and samarium ions doped into a variety of chalcogenide glass hosts. Potential electro-optic traps in chalcogenide glass hosts, as well as optical traps, are discussed for the first time.
