Abstract

The ability to synthesize complex femtosecond optical waveforms to desired specifications via pulse shaping methods is now well established. ¹⁻³ As typically employed, the temporal profile of the output waveform is determined by the Fourier transform of the spatial pattern transferred by a fixed mask or modulator array unto the dispersed optical spectrum utilizing bulk optical components.^1,2 Only limited work has been reported on integrated optic implementations of pulse shapers³⁻³ typically based on arrayed waveguide gratings (AWG’s).⁵ We recently reported on an integrated optic configuration⁴ of a femtosecond pulse shaping apparatus closely related to the direct space-to-time pulse shaper.²
