We generated time-multiplexed degenerate optical parametric oscillator (DOPO) pulses using a nonlinear fiber Sagnac interferometer as a phase-sensitive amplifier (PSA). Here, we confirmed the phases of the DOPO pulses were bifurcated to 0 or π, which makes them useful for simulating Ising spins. The inherent randomness of the DOPO phases was confirmed by using the NIST random number test too.
