• Authors: Linh Nguyen, Jamison Sloan, Nicholas Rivera, Marin Soljacic
• Abstract summary: We introduce a new concept which uses gain to generate intense sub-Poissonian light at optical frequencies. The interaction between the gain medium and Kerr nonlinearity suppresses the spontaneous emission at high photon number states. We show how 90% squeezing of photon number fluctuations below the shot noise level can be realized.

• Abstract: Non-classical states of light, such as number-squeezed light, with fluctuations below the classical shot noise level, have important uses in metrology, communication, quantum information processing, and quantum simulation. However, generating these non-classical states of light, especially with high intensity and high degree of squeezing, is challenging. To address this problem, we introduce a new concept which uses gain to generate intense sub-Poissonian light at optical frequencies. It exploits a strongly nonlinear gain for photons which arises from a combination of frequency-dependent gain and Kerr nonlinearity. In this laser architecture, the interaction between the gain medium and Kerr nonlinearity suppresses the spontaneous emission at high photon number states, leading to a strong "negative feedback" that suppresses photon-number fluctuations. We discuss realistic implementations of this concept based on the use of solid-state gain media in laser cavities with Kerr nonlinear materials, showing how 90% squeezing of photon number fluctuations below the shot noise level can be realized.

In particular, non-trivial quantum states of harmonics are generated as soon as one of the harmonics induces a transition between different laser-dressed states of the material system. Our analysis opens remarkable opportunities at the interface of attosecond physics and quantum optics, with implications for quantum information science.

  We introduce a class of driven-dissipative systems in which a nonlinear cavity experiences non-Markovian coupling to the outside world. In the classical regime, we show that these non-Markovian cavities can have extremely low thresholds for nonlinear effects. In the quantum regime, we show how these system, when implemented on state-of-the-art platforms, can enable generation of strongly squeezed cavity states.

  Light and matter can now interact in a regime where their coupling is stronger than their bare energies. We show how light and matter interactions in this regime give rise to electromagnetic nonlinearities. This nonlinearity forms the basis for a new type of gain medium, which when integrated into a laser or maser, produces large Fock states.
