چکیده

Arsenic chalcogenide microlenses (As2S3) produced by an original procedure have been used for focusing the red – infrared laser light direct through an optical fiber. The microlenses with diameter in the range 150 – 400 m were glued on the optical single-mode fiber ends by Canada balm under optical microscope. The focusing effect of the microlenses was investigated in a stereomicroscope, and the focusing quality was studied with the radiation of a He-Ne laser.

Microstructure, mechanical and thermal properties of chalcogenide glasses and glass-ceramics based on Se-As-Ge system nucleated by Sn

In particular, chalcogenide glasses and glass-ceramics are new materials that exhibit good transparency in infrared region (0.8-12µm). We can overcome the main weakness of these glasses by improving the hardness through controlling crystallization. In this paper, we report results of a study on chalcogenide glasses in the ternary system of As-Se-Ge with nominal composition of Snx (Se...

Nonlinear characterization of robust multimaterial chalcogenide nanotapers for infrared supercontinuum generation

Wepresent the results of an investigation of the nonlinear characteristics of a new class of robust,multimaterial, allsolid chalcogenide nanotapers prepared from high-index-contrast chalcogenide fibers. The fiber is drawn from a preform produced bymultimaterial coextrusion and consists of chalcogenide core and cladding (which dictate the optical properties) and a built-in thermally compatible p...

Linear and nonlinear optical properties of chalcogenide microstructured optical fibers

Chalcogenide glasses are known for their large transparency in the mid-infrared and their high linear refractive index (>2). They present also a high non-linear coefficient (n2), 100 to 1000 times larger than for silica, depending on the composition. we have developed a casting method to prepare the microstructured chalcogenide preform. This method allows optical losses as low as 0.4 dB/m at 1....

Photonic Bandgap Propagation in All-Solid Chalcogenide Microstructured Optical Fibers

An original way to obtain fibers with special chromatic dispersion and single-mode behavior is to consider microstructured optical fibers (MOFs). These fibers present unique optical properties thanks to the high degree of freedom in the design of their geometrical structure. In this study, the first all-solid all-chalcogenide MOFs exhibiting photonic bandgap transmission have been achieved and ...
