摘要

Record squeezing, with squeezing parameter $r\approx 2.5$ is measured in AlGaAs optical parametric amplifiers using an ultrafast pump centered at 775 nm. Polarization dependent squeezing and parametric gain were obtained with sub-photon per pulse amplifier sensitivity at 1550 nm regime. © 2019 The Author(s)
