First, we checked BAB and LO alignment inside the AMC.

LO mode-matching is about 99.9% and BAB is 99.12 +/- 0.3 %.

We measured visibility by installing a PD before the AMC and got 95 +/-1.7 %, but we expect to find same value as mode-mismatch into the AMC..

We then measured the visibility directly from the homodyne and got 98.1 +/- 0.4%.

While this value is closer, there is still some discrepancy and we are not so sure about the reason for that.

We measured squeezing and anti-squeezing with higher pump power (45mW, 50 mW, 55 mW).

The result is attached in figure 1.

From the fit, we have optical losses = 20.74 +/- 1.16 % and phase noise = 34.64 +/-3.15 mrad.

We tuned PLL frequency and OPO temperature before each measurement but forgot to record their values..
