Abstract

The analysis here applies to a nonlinearity with the refractive index represented by n=n₀ + (n₂′ + ın₂″) I, where n₂′ is the real (dispersive) and n₂″ is the imaginary (absorptive) part of the nonlinear refractive index n₂. An exact theoretical treatment has been given for the NDTWM including only the dispersive nonlinearity (n₂″=0)¹. This has been extended to include nonlinear absorption through a holographic or grating term².
