| Abstract: | A technique is proposed and demonstrated for measuring the waveforms of optical signals by making use of homodyne in-phase and quadrature detection combined with nonlinear optical sampling. The technique is based on time division sampling of electric field components with a discretely phase-modulated local oscillator light and is applied for the evaluation of the ultrafast response in a semiconductor optical amplifier. |
