  We demonstrate a squeezing experiment exploiting the association of
integrated optics and telecom technology as key features for compact, stable,
and practical continuous variable quantum optics. In our setup, squeezed light
is generated by single pass spontaneous parametric down conversion on a lithium
niobate photonic circuit and detected by an homodyne detector whose
interferometric part is directly integrated on the same platform. The remaining
parts of the experiment are implemented using commercial plug-and-play devices
based on guided-wave technologies. We measure, for a CW pump power of 40\,mW, a
squeezing level of $-2.00\pm0.05$\,dB, (antisqueezing $+2.80\pm0.05$\,dB) thus
confirming the validity of our approach and opening the way toward miniaturized
and easy-to-handle continuous variable based quantum systems.
