In this paper,we present a novel ultrashort pulse shaper based on complex-modulated long-period-grating coupler(CM-LPGC).Temporal rectangular waveform with 2-ps full width at half maximum(FWHM) is obtained by transforming the input Gaussian pulse.Tolerances of the CM-LPGC-based shaper to various non-ideal excitation conditions and fabricating errors are investigated.Results confirm that CM-LPGC is stable and suitable for optical pulse shaping operation.
