Abstract
Non-Resonant Optical Nonlinearity of Germano-Silicate Optical Fiber Incorporated with Si Nanocrystals Hye Jin Cho, Aoxiang Lin, Songbae Moon and Won-Taek Han Department of Information and Communications, School of Photon Science and Technology, Gwangju Institute of Science and Technology, Gwangju 500-712 Bok Hyeon Kim Advanced Photonics Research Institute, Gwangju Institute of Science and Technology, Gwangju 500-712 (Received 12 December 2007) The non-resonant optical nonlinearity of a germano-silicate glass optical ber with silicon (Si) nanocrystals incorporated, fabricated by using a modi ed chemical vapor deposition process, was investigated by the continuous-wave self-phase modulation method. The measured non-resonant nonlinear refractive index, n2 = 5:70 10 20 m2/W, of the ber was found to be 2 times larger than that of the ber without Si incorporation.
