Generation of 12 dB squeezed light from a waveguide optical parametric amplifier using a machine-learning-controlled spatial light modulator

Gyeongmin Ha, Kazuki Hirota, Takahiro Kashiwazaki +5

We demonstrate the generation of $12.1\pm 0.2$ dB squeezed light from a periodically poled lithium niobate (PPLN) waveguide optical parametric amplifier (OPA). While single-pass O…
