The optical domain optical signal sampling device comprises an electrical sampling pulse source and an electrically-controlled optical modulator. The electrically-controlled optical modulator comprises electro-optical material, an optical waveguide located in the electro-optical material and including a bifurcated region, and electrodes disposed along the bifurcated region. The optical waveguide is arranged to receive an optical signal-under-test. At least one of the electrodes is connected to receive electrical sampling pulses from the electrical sampling pulse source. The electrical sampling pulses generate an electric field between the electrodes that differentially changes the refractive index of the electro-optical material in the bifurcated region of the optical waveguide to sample the optical signal-under-test.
