Linear and nonlinear optical properties of the PbSe quantum dots doped germano-silica glass optical fiber

Abstract

We report development of a new fiber doped with PbSe quantum dots for nonlinear optical applications. PbSe quantum dots related absorption peaks were obtained at 1021, 1093 and 1351 nm. The resonant optical nonlinearity and attenuation at 1500 nm were measured to be 9.4 × 10- 16 m2/W and 0.01 dB/m, respectively. The emission around 1540 nm was observed upon near resonant pumping at 1064 nm. © 2010 Elsevier B.V. All rights reserved.
