摘要：

Self-phase modulation due to fibre nonlinearity can result in significant composite second order distortion in externally modulated AM-SCM video systems. However, it is shown that this can be minimised by phase modulating the optical carrier. Analytic expressions are derived which are in good agreement with numerical simulations.
