Transverse Anderson localization of mid-infrared light in a chalcogenide transversely disordered optical fiber

Abstract

We successfully fabricate a transversely disordered optical fiber made of AsSe2 and As2S5 glasses for high-resolution mid-infrared image transport. By using the fabricated fiber, we experimentally observe transverse Anderson localization of mid-infrared light at the wavelength of 3 µm. Moreover, we numerically evaluate the localization in the fiber by using a cross-sectional image of the fiber.

Numerical investigation of cross-talk in chalcogenide triangular lattice fibers with three sublattices for mid-infrared image transport

“…Owing to the thermal stability, many fiber fabrications using the glass pair have been successful. [27][28][29] The refractive indices of the cores and the cladding are 2.6984 and 2.2298, respectively, at a working wavelength of 9.3 μm. The working wavelength is a peak wavelength of radiation at a human body temperature of about 37 °C.…”
