Abstract :In this study, the variation of the dielectric constant, i.e. relative permittivity of highly doped-silica glass used in optical fibers with frequency and temperature under the effect of polarization has been investigated. In this context, simulations of the relationship between the dielectric constant and both frequency and temperature have been carried out in the Matlab environment. According to simulation and theoretical analysis, it has been concluded that the dielectric constant of highly doped-silica glass tends to increase with the increase of ambient temperature. On the other hand, as the frequency of the source increases linearly, the dielectric constant decreases. Hence, the variations of highly doped-silica glass with temperature and frequency have been found to be 2.884 × 10-5 (°K)-1 and – 7.50 × 10-15 (Hz)-1, respectively. Moreover, in response to the change in frequency between 1011 Hz and 1012 Hz, the dielectric constant has taken values between 2.085 and 2.070. Additionally, for dielectric constant variations in 2.070 – 2.085 range, values of the relative change in polarization have been obtained in the range of 9.4695 × 10-12 F/m – 9.6023 × 10-12 F/m.
