研究目的
To obtain a basic equation that governs propagation of optical pulses in single-mode fibers by considering the theory of electromagnetic wave propagation in dispersive nonlinear media.
研究成果
The chapter successfully derives a basic equation governing the propagation of optical pulses in single-mode fibers, incorporating both linear and nonlinear effects. It also discusses the numerical methods necessary for solving this equation, providing a foundation for understanding nonlinear phenomena in optical fibers.
研究不足
The chapter focuses on single-mode fibers and assumes the spectral width of the pulse is much smaller than the frequency of the incident radiation. The analysis may not fully account for all nonlinear effects in fibers with more complex structures or under extreme conditions.
