Observation of Non-Markovian Radiative Phenomena in Structured Photonic Lattices.

Area of Science:

• Quantum Optics
• Condensed Matter Physics
• Photonic Systems

Background:

• The spectral properties of a photonic reservoir significantly influence the radiation dynamics of embedded quantum emitters.
• Understanding non-Markovian dynamics is crucial for controlling quantum light-matter interactions.

Purpose of the Study:

• To investigate the impact of structured photonic reservoirs on quantum emitter radiation phenomena.
• To experimentally explore non-Markovian radiation dynamics using an all-optical analog.

Main Methods:

• Implementation of an all-optical analog simulating a quantum emitter coupled to a two-dimensional structured photonic reservoir.
• Simulation of emitter dynamics via light propagation in photonic lattices (square and Lieb lattices).
• Analysis of radiation dynamics under varying coupling regimes.

Main Results:

• Observation of enhanced light-matter coupling and non-Markovianity in Lieb lattices due to their flat band properties.
• Demonstration of how spectral structure in photonic reservoirs shapes radiation phenomena.
• Validation of the all-optical analog for studying quantum optical phenomena.

Conclusions:

• The spectral structure of photonic reservoirs is a key factor in controlling quantum emitter radiation.
• Lieb lattices offer a promising platform for enhancing light-matter interactions and non-Markovian effects.
• The developed all-optical analog provides a valuable tool for future experimental studies in quantum optics.
