Abstract :
A general formula is given for frequency chirping of external intensity loss modulation which is caused by phase modulation due to an accompanied refractive index change. It can be reduced by optimising the optical modulation waveform, and a related ultimate bandwidth of such small chirping single-mode fibre transmission will be presented.
