Fictive temperature in silica-based glasses and its application to optical fiber manufacturing

Progress in Materials Science (Impact Factor: 27.42). 01/2012; 57(1):63-94. DOI: 10.1016/j.pmatsci.2011.05.002

ABSTRACT

This paper will thus give an overview of methods to reduce efficiently the Rayleigh scattering loss via the fictive temperature in silica-based optical fibers. We will first recall what the concept of fictive temperature Tf is and its limitations in section 2. We will see that both Raman and IR spectroscopy can be used to determine Tf (Section 3). Section 4 will thus give some examples of Tf profiles measured in optical fibers manufactured in different conditions. Finally, section 5 will present the main approaches to reduce Rayleigh scattering loss in silica-based fibers via a reduction of Tf.
