摘要: The nonlinear dependence of the parametric gain for small-signal amplification is experimentally studied in a normally dispersive highly birefringent single-mode fibre. As result pump-induced phase shift, signal curve versus pump power bell shaped undepleted-pump regime with maximum attained away from perfect phase-matching. This dynamics quite different quasi-exponential measured spontaneous emission growing noise. Moreover, experimental curves are more accurately predicted by modulation instability computations rather than four-wave mixing theory because influence non-phase-matched waves.
