We describe the calibration method and present a full calibration of an InP-based monolithically integrated optical pulse shaper. The 6×6mm2 chip includes an arrayed waveguide grating separating the spectrum into 20 channels where each channel has an electro-optic phase modulator and an optical amplifier. The calibration method is based on interferometric analysis and is applied to characterize the amplitude and phase of individual device channels as well as the total system response. The calibration information is required for producing predictable pulse shapes.
