Kerr nonlinearity of Thulium-doped fiber near 2 μm [PDF]

CLEO: 2015, 2015
The nonlinear coefficient and group velocity dispersion of a thulium-doped fiber near 2μm are evaluated via four-wave mixing. Nonlinearity of thulium-doped fiber can be used for the design of doped-fiber lasers in this spectral region.
