  Squeezed light is a key quantum resource that enables quantum advantages for
sensing, networking, and computing applications. The scalable generation and
manipulation of squeezed light with integrated platforms are highly desired for
the development of quantum technology with continuous variables. In this
letter, we demonstrate squeezed light generation with thin-film lithium niobate
integrated photonics. Para-metric down-conversion is realized with quasi-phase
matching using ferroelectric domain engineering. With sub-wavelength mode
confinement, efficient nonlinear processes can be observed with single-pass
configuration. We measure0.56+-0.09dB quadrature squeezing(~3 dB inferred
on-chip). The single-pass configuration further enables the generation of
squeezed light with large spectral bandwidth up to 7 THz. This work represents
a significant step towards the on-chip implementation of continuous-variable
quantum information processing
