title: Development of Germano-Silicate Optical Fiber Incorporated with Germanium Nanoparticles and Its Optical Characteristics.
abstract: The germano-silicate optical fiber incorporated with Ge nanoparticles with enhanced optical nonlinearity was developed by using modified chemical vapor deposition and drawing processes. A broad photoluminescence band obtained by pumping with the 404 nm superluminescent diode was found to appear from 540 nm to 1,000 nm. The non-resonant nonlinear refractive index, n2, of the fiber measured by the continuous wave self-phase modulation method was 4.95 x 10(-20) m2/W due to the incorporated Ge nanoparticles in the fiber core. The enhancement of the non-resonant optical non-linearity may be due to the creation of the NBOs and other defects from the incorporated Ge-NPs in the fiber core.
