Experimental Measurements of the Rate of Change of the Index-of-Refraction of Optical Fiber Materials with Respect to Temperature and Pressure.
Abstract
Laser interferometry was employed to determine the rate of change of the index of refraction with respect to temperature and pressure, the expansion coefficient and the compressibility of doped-silica glass samples for three types of dopants and different dopant concentration for a given dopant. Two fused silica samples were also included in the optical measurements to check the validity of the experimental method and to establish baseline values for the quantities being measured. Water was used as thermal bath for the temperature measurements and as the compressive fluid for the pressure measurements.
