Abstract

In this work, the viscoelastic behavior of a polymeric step-index optical fiber is studied, and the loss factors η of their complex moduli are calculated. The loss factors of the Young and shear moduli were determined from the measurement of the damping ratio γ of a simple pendulum and a torsion pendulum respectively, using the Kelvin-Voigt model of the viscoelastic theory. The shear and Young complex moduli can be used to study the optic-viscoelastic behavior of a polymeric step-index optical fiber.
