We demonstrated time-domain measurement and frequency domain measurement of continuous-variable (CV) entanglement with pulsed light source and waveguides. The experiment with pulsed light source has difficulty in temporal mode matching between the entangled beams and local oscillator (LO) beams. To break through this difficulty, we shorten the duration of LO pulse by optical parametric amplification (OPA) in a waveguide. We generated entanglement that satisfied EPR-Reid criterion in the time domain measurement.
