Fiber with negative curvature of the hollow core of polymeric material: production and research of optical properties

Researches of optical properties of polymeric glass of polymethyl methacrylate brand (Evonik Industries) in the form of volume samples and the microstructured optical fibers by measurement of transmission ranges in the range of lengths of waves of 250-1700 nm are conducted. The optical fiber having a hollow waveguide core and a cover of microcapillaries of the same kind is made by "stake and draw " method. It is demonstrated that fiber of the considered design structure allows to expand the wave range of a transmission in near infrared area of a spectrum, weaking less, than material absorption of polymer in the form of a volume sample.
