Abstract

A tellurium-doped germanosilicate optical fiber was developed by modified chemical vapor deposition and solution doping techniques. Using the continuous-wave self-phase modulation method, the nonresonant nonlinear refractive index, n 2 , was measured to be 5.52 × 10 20 m 2 / W , which is 2 to 3 times that of the undoped germanosilicate glass fiber. Polyhedron structures Te O 3 and Te O 4 with Ge O 4 and Si O 4 are believed responsible for lower phonon energy, more nonbridging oxygens, and a larger hyperpolarization, leading to the observed higher nonresonant optical nonlinearity.
