Abstract :
The effect of laser linewidth on the crosstalk penalty in a two-channel ASK heterodyne system is calculated through a simple frequency domain analysis. The results show that the crosstalk penalty increases steeply when the linewidth at the IF stage exceeds one-tenth of the bit rate. The results of calculation show very good agreement with experiment by Park et al
