In this paper, the optical properties of available-on-market fluoride glass fibers are examined in order to understand their potentialities in a lot of application areas. The investigation is made with reference to several glass characteristics, in order to appreciate how the change of ZBLAN chemical composition can be exploited to tailor the refractive index and the dispersion. Higher order dispersion coefficients are calculated and are inserted in a home-made computer code in order to simulate supercontinuum (SC) generation in ZBLAN fibers, by using the generalized nonlinear Schrödinger equation (GNLSE) at an emission wavelength equal to 2.9 μm, which is typically used for medical application. As first result, a broadband spectrum extending beyond 4.4 μm is predicted.

Abstract

In this paper, the optical properties of available-on-market fluoride glass fibers are examined in order to understand their potentialities in a lot of application areas. The investigation is made with reference to several glass characteristics, in order to appreciate how the change of ZBLAN chemical composition can be exploited to tailor the refractive index and the dispersion. Higher order dispersion coefficients are calculated and are inserted in a home-made computer code in order to simulate supercontinuum (SC) generation in ZBLAN fibers, by using the generalized nonlinear Schrödinger equation (GNLSE) at an emission wavelength equal to 2.9 μm, which is typically used for medical application. As first result, a broadband spectrum extending beyond 4.4 μm is predicted.
