Fundamental Equations
摘要
This chapter will discuss the fundamental equations of the nonlinear propagation and spectral coherence. It further illustrates different forms of NLSE in detail, including the simplified equations of NLSE for longer ps or CW pump; the generalized formation of NLSE including higher-order nonlinear and dispersive effects for fs pulse; the GNLSE with complex nonlinear parameters involving TPA, FCA and FCD for the characteristics of integrated waveguides.
