Design and optimization of tellurite hybrid microstructured optical fiber with high nonlinearity and low flattened chromatic dispersion for optical parametric amplification
2014
Abstract The linear phase-mismatch and the optical signal gain in the highly nonlinear tellurite hybrid microstructured optical fiber based on the degenerate four-wave mixing are numerically simulated. The core and the cladding of this fiber are designed by TeO 2 –Li 2 O–WO 3 –MoO 3 –Nb 2 O 5 and TeO 2 –ZnO–Na 2 CO 3 –P 2 O 5 glass, respectively. This fiber has high nonlinearity and at the same time the chromatic dispersion is flattened and close to zero. High optical signal gain and broad band can be obtained by using a short length of this fiber with low pump power.
