Abstract :
Incident-power-dependent extinction ratio of electroabsorption modulators is shown and theoretically investigated by using microscopic theory combined with heat-flux calculation. The phenomenon stems from voltage-dependent temperature rise and the calculated results agree well with the experiment.
