Abstract

We demonstrate a plug-and-play squeezing experiment entirely based on lithium-niobate integrated optics and commercial fiber components. We achieve −2 dB of squeezing confirming the validity of this original approach that opens to out-of-the-lab continuous-variable experiments.

Chip-Based Compact Squeezing Experiment at a Telecom Wavelength

François Mondain, Tommaso Lunghi, Alessandro Zavatta +5 more

In the context of quantum communication and technologies squeezed states of light represent a crucial resource. Nevertheless, their generation and detection usually demand complex bulk systems, hardly compatible with out-of-the-laboratory realizations. In view of future practical applications, we present a compact and easy-to-use set-up exploiting the association of commercial plug-and-play fibre components and integrated optics on lithium niobate for the generation and detection of squeezed light at a telecom wavelength. Squeezed light exhibits a reduced quantum noise of -2.00 ± 0.05 dB below the shot-noise level in a single-pass configuration.

Chip-based squeezing at a telecom wavelength

François Mondain, Tommaso Lunghi, Alessandro Zavatta +5 more

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.

Squeezed Light Generation in Periodically Poled Lithium Niobate Nanophotonic Waveguide

Xiaodong Shi, Angela Anna Baiju, Sakthi Sanjeev Mohanraj +8 more

We demonstrate an on-chip telecom-wavelength squeezer using a periodically poled thin-film lithium niobate waveguide. With a single-pass, continuous-wave pump at 49 mW, we measure -0.64 dB squeezing and 4.30 dB anti-squeezing (11 dB inferred on-chip).
