Abstract

The invention discloses an As2SexS3-x ternary semiconductor core composite optical fiber with a phosphate glass cladding, and a preparation method for the As2SexS3-x ternary semiconductor core composite optical fiber. The cladding material of the composite optical fiber is phosphate glass, and the fiber core of the optical fiber is made of As2SexS3-x, wherein x is greater than zero and is less than three. According to the invention, the optical fiber combines the excellent photoelectric performances of phosphate glass and As2SexS3-x, so the optical fiber is good in photoelectric performance, has good permeability and high nonlinearity at the near, middle and far infrared bands, and has great application prospect in the fields of non-linear optics, photoelectric detection, biomedical sensing, infrared laser transmission or super-continuum spectrum light sources. The optical fiber makes the reasonable use of the wetness and thermal expansion of the optical fiber cladding and the fire core, takes the phosphate glass as the optical fiber cladding, takes As2SexS3-x as the optical fiber core, is drawn through a melting method, and can be continuously drawn.
