- Abstract: This work reports a fully guided setup for single-mode squeezing generation
on integrated titanium-indiffused periodically poled nonlinear resonators. A
continuous wave laser beam is delivered and the squeezed field is collected by
single-mode fibers, where up to -3.17(9) dB of useful squeezing is available in
fibers. To showcase the usefulness of such a fiber-coupled device, we applied
the generated squeezed light in a fiber-based phase sensing experiment, showing
a quantum enhancement in the signal-to-noise ratio of 0.35 dB. Moreover, our
investigation of photorefraction's impact on the cavity resonance condition
suggests that it causes system instabilities at high powers.

A continuous-wave (CW) broadband high-level optical quadrature squeezer is essential for high-speed large-scale fault-tolerant quantum computing.
We fabricated a low-loss quasi-single-mode periodically-poled LiNbO3 waveguide, which shows 7% optical propagation loss with a waveguide length of 45 mm.
Thanks to its directly bonded core on a LiTaO3 substrate, the waveguide does not show pump-induced optical loss even under a condition of hundreds of milliwatts pumping.
