A novel fabrication technique by composite material processing: Integrated metal-insulator-semiconductor fibers and fiber devices

Abstract

ABSTRACTFabrication of functional devices in fibers by thermal drawing requires a material identification scheme and challenging composite material processing. A macroscopic preform rod containing metallic, semiconducting and insulating constituents in a variety of geometries and close contact leads to kilometer-long novel optoelectronic, and thermal mesoscopic fiber devices. The preform-to-fiber approach yields spectrally tunable photodetectors and integrated self-monitoring fibers.
