Jaynes-Cummings photonic superlattices.

Area of Science:

• Quantum optics
• Condensed matter physics
• Quantum information science

Background:

• The Jaynes-Cummings (JC) model describes fundamental light-matter interactions.
• Exploring the deep strong coupling regime of the JC model is experimentally challenging.
• Classical analogs can provide novel insights into quantum phenomena.

Purpose of the Study:

• To propose a classical optical system that realizes the Jaynes-Cummings (JC) model.
• To visualize and understand dynamical regimes in the JC model not previously accessible.
• To gain new physical insights into the deep strong coupling regime.

Main Methods:

• Utilizing light transport in engineered waveguide superlattices.
• Mapping quantum states and dynamics onto an optical analog.
• Analyzing photon number wave packet dynamics and population revivals.

Main Results:

• A classical realization of the JC model is demonstrated using waveguide superlattices.
• The optical system allows visualization of Fock space dynamics.
• Photon number wave packet bouncing and population revivals are observed and explained.

Conclusions:

• The proposed optical system provides a powerful tool for studying the JC model.
• Generalized Bloch oscillations in an inhomogeneous tight-binding lattice explain observed dynamics.
• This work offers new perspectives on the deep strong coupling regime of quantum optics.
