We have fabricated an optoelectronic sampling circuit for direct measurement of picosecond optical waveforms. The monolithic device incorporates a GaAs Schottky photodetector and a high-speed sampling circuit gated by a nonlinear transmission line strobe pulse generator. Excited by an 850 nm model-locked dye laser, a 5.6 ps FWHM impulse response is measured we estimate a deconvolved impulse response of approximately 4.5 ps FWHM.
