We generated 2.2 dB of broadband amplitude squeezing at 1064 nm in a periodically poled K Ti O P O 4 (PPKTP) waveguide by coupling of the fundamental and second-harmonic cw fields. This is the largest amount of squeezing obtained to date in a KTP waveguide, limited by propagation losses. This result paves the way for further improvements by use of lower-loss buried ion-exchanged waveguides.
