Abstract

The invention discloses a metal-semiconductor-glass opto-electronic optical fiber and a preparation method thereof. The opto-electronic optical fiber comprises a cladding (2), a fiber core (3) and metal aluminum wires (1), wherein the cladding (2) is phosphate glass; the fiber core (3) is arranged on an axis of the optical fiber and refers to selenium-tellurium semiconductor spheres distributed at intervals; two metal aluminum wires (1) which are symmetrically distributed are arranged on two sides of the fiber core (3) by taking the fiber core (3) as an axis of symmetry; the metal aluminum wires (1) are parallel to the fiber core (3) along the axis direction of the optical fiber; and the metal aluminum wires (1) and the selenium-tellurium semiconductor spheres in the fiber core (3) are in direct contact so as to form an electrical circuit. The method comprises the following steps: preparing an optical fiber preform, performing wire drawing, and performing heat treatment, thereby obtaining the opto-electronic optical fiber. The opto-electronic optical fiber disclosed by the invention integrates high photoconductive property of the selenium-tellurium semiconductor and conductivity of the metal aluminum, the current change in the dark and under the light reaches two orders of magnitudes or more, and the change of light current can be regulated by regulating selenium-tellurium components.

Description

technical field [0001] The invention relates to the field of optical fiber preparation, in particular to a metal-semiconductor-glass photoelectric optical fiber and a preparation method thereof. Background technique [0002] In 2004, American scientists Fink et al. (M.Bayindir, F.Sorin, A.F.Abourady, et al., Nature, 2004, 431(7010):826-829.) prepared the metal-semiconductor- Polymer photoelectric fiber, this new type of composite fiber is made of low melting point metal tin (Sn), amorphous sulfide semiconductor (As-Se-Te-Sn or As 2 Se 3 ) and polymers (PEI or PES), which integrates the rich electrical and optoelectronic properties of semiconductors, the electrical conductivity of metals and the flexibility and braidability of optical fibers, and is expected to be used in smart fabrics, photoelectric detection and temperature sensing. In 2006, American scientist Badding and British scientist Sazio and others used high-pressure chemical vapor deposition to selectively deposi...

Problems solved by technology

However, the previous work did not integrate metal electrodes into the optical fiber. The optical fiber can only conduct electricity through semiconductors, and the conductivity is low, so it cannot become a true optoelectronic optical fiber.
