Heterodyne technique for measuring the amplitude and phase transfer functions of an optical modulator
In this letter, we propose a technique based on heterodyne detection for accurately and simultaneously measuring the amplitude and phase transfer functions of an optical modulator. The technique is used to characterize an InGaAsp multiple quantum-well electroabsorption modulator. From the measurements we derive the small-signal alpha-parameter and the time-dependent chirp for different operation conditions.
