Towards high-strength infrared optical fibers for bio-sensing (Conference Presentation)

Chalcogenide glasses exhibit excellent transparency in the mid infrared wavelength range which make them unique candidates for the fabrication of complex optical elements for bio-sensing. However, one of the main shortcomings of chalcogenide glasses compared to their oxide counterpart is their relatively poor mechanical strength. Nevertheless, the rapid development of infrared technology has raised the need for robust infrared fibers suitable for use in demanding environments. Here we report the development of triple index hybrid fibers composed of a chalcogenide core-clad structure embedded in an oxide external cladding.
