Journal Article
Nunes, J. J., Sojka, Ł., Crane, R. W., Furniss, D., Tang, Z. Q., Mabwa, D., …Sujecki, S. (2021). Room temperature mid-infrared fiber lasing beyond 5  µm in chalcogenide glass small-core step index fiber. Optics Letters, 46(15), 3504-3507. https://doi.org/10.1364/ol.430891

We report mid-infrared fiber lasing for the first time above 5 µm in a room temperature, Ce 3+ doped, chalcogenide glass, step index fiber using in-band pumping with a 4.15 µm quantum cascade laser. The lasing fiber is 64 mm long, with a calculated n... Read More about Room temperature mid-infrared fiber lasing beyond 5  µm in chalcogenide glass small-core step index fiber.

Internal examination of mid-infrared chalcogenide glass optical fiber preforms and fiber using near-infrared imaging (2021)
Journal Article

Internal examination of mid-infrared chalcogenide glass optical fiber preforms and fiber using near-infrared imaging. Optical Materials Express, 11(5), 1353-1363. https://doi.org/10.1364/OME.415518

We report on the internal examination of mid-infrared chalcogenide glasses using near-infrared light to reveal light-scattering defects. The technique is demonstrated on imperfectly made chalcogenide glass rods and fiber. This simple, non-destructive...

Thermal nanoimprinting is a fast and versatile method for transferring the anti-reflective properties of subwavelength nanostructures onto the surface of highly reflective substrates, such as chalcogenide glass optical fiber end-facets. In this paper... Read More about Thermo-mechanical Dynamics of Nanoimprinting Anti-Reflective Structures onto Small-core Mid- IR Chalcogenide Fibers.

Evaluating the cytotoxicity of Ge–Sb–Se chalcogenide glass optical fibres on 3T3 mouse fibroblasts (2021)
Journal Article

In vivo cancer detection based on the mid-infrared molecular fingerprint of tissue is promising for the fast diagnosis and treatment of suspected cancer patients. Few materials are mid-infrared transmissive, even fewer, which can be converted into fu...
