We experimentally demonstrate amplitude and phase modulation of a time-energyentangled two-photon wave function. The entangled photons are produced byspontaneous parametric down-conversion, spectrally dispersed in an prismcompressor, modulated in amplitude and/or phase, and detected in coincidence bysum-frequency generation. First, we present a Fourier optical analysis of theoptical setup yielding an analytic expression for the resulting fielddistribution at the exit plane of the shaping apparatus. We then introduceamplitude and/or phase shaping and present results which can only be obtainedthrough a combination of the two. Specifically, we use a shaper-basedinterferometer to measure the two-photon interference of an almostbandwidth-limited two-photon wave function.
