Abstract

We report on the first realization of an entirely guided-wave squeezing experiment at telecom wavelength. Our setup exploits non-linear optical waveguides and fiber components. This configuration allows implementing a plug-and-play experiment, compatible with fiber networks.

A fully guided-wave squeezing experiment for fiber quantum networks

Florian Kaiser, Bruno Fedrici, Alessandro Zavatta +2 more

We demonstrate, for the first time, the realization of an entirely guided-wave squeezing experiment at a telecom wavelength. The state generation relies on waveguide non-linear optics technology while squeezing collection and transmission are implemented by using only telecom fibre components. We observe up to $-1.83\pm0.05$ dB of squeezing emitted at 1542 nm in CW pumping regime. The compactness and stability of the experiment, compared to free-space configurations, represent a significant step towards achieving out-of-the-lab CV quantum communication, fully compatible with existing telecom fibre networks. We believe that this work stands as a promising approach for real applications as well as for "do-it-yourself" experiments

We demonstrate a plug-and-play squeezing experiment entirely based on off-the-shelves guided-wave components and lithium-niobate integrated optics. We achieve −2 dB of squeezing thus validating our original approach as a ressource for real-world continuous-variable implementations.

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.
