Abstract

The conditions leading to the recent observation of efficient upconversion of 1319-nm radiation to 580 nm in SiO₂ single-mode fiber are examined. Simulation results, based on the third-order nonlinearity and the waveguiding characteristics of typical fiber, show that the visible signal may be generated by phase-matched four-wave mixing within the concurrently generated infrared spectral continuum.
