Description
With quantum squeezing emerging as an essential technology for gravitational wave detectors and quantum metrology, there are ongoing efforts to develop compact broadband sources. We report over −3.0 dB of broadband squeezing at 1064 nm using a periodically-poled lithium niobate (PPLN) waveguide crystal. Using a single pass through the waveguide, squeezing is observed from the MHz range all the way down to a few kHz with only 120 mW of pump power. In addition, we implement a novel quantum phase-locking scheme to stabilize the squeezed field. With demonstration of low-power compact squeezing generation, this may be an avenue for future gravitational-wave detection.
