Evolutive Optical Fibers Combining Oxide and Chalcogenide Glasses with Submicronic Polymer Structures

Multimaterial optical fibers combining tellurite with chalcogenide glasses and featuring thin polymer structures are fabricated via the thermal drawing process. It is demonstrated that micrometric polyethersulfone films can be embedded within larger elongated tellurite/chalcogenide glass architectures. Taking advantage of strong chemical reactivity contrasts which exist in considered fiber geometries, a quasi-exposed-core waveguide obtained by selective etching cladding. The potential postprocessed structure then assessed through evanescent-wave probing liquids numerical investigations carried out to establish device performances as function selected optogeometric parameters. Those results open way for development evolutive photonic objects benefiting from postdrawing processing multimaterial fibers.
