Engineering Collective Interactions in Solid-State Arrays.
Our recent research has focused on engineering arrays of active optical centers to effectively control the interaction Hamiltonian between light and matter. The collective interaction of atomic arrays with optical photons offers directionally enhanced absorption or emission, facilitating the development of robust atom-photon interfaces with broad bandwidths. Our study specifically investigates long-range cooperative resonances in an array of rare-earth ions that are controllably implanted into a solid-state photonic resonator. By exploring the enhanced interactions resulting from both cavity-induced Purcell effect and array-induced collective resonances at cryogenic temperatures, we aim to establish a new paradigm for enhanced light-matter interactions. This innovative approach holds promise for suppressing spontaneous emission and ultimately paving the way for novel photonic device advancements.

Heterogeneous Photonic Integration and Nanofabrication.
Rare earth ions (REIs) in solids have many applications in nonlinear optics including lasers and optical amplifiers due to their stable optical transitions and long lifetimes. REIs also feature long nuclear spin coherence times and weak coupling to external radiation, which are attractive features for applications in quantum information processing. The crystalline solids incorporated with quantum centers such as REIs enable the miniaturization of quantum optical elements which will play a key role in the implementation of future multiplexed quantum optical networks. To date, the integration of nanophotonic resonators on bulk rare earth crystals resulted in the demonstration of quantum storage, single-photon generation, strong atom-photon interactions, and quantum transduction.
Motivated by recent progress in lithium niobate and silicon-photonic nanofabrication, we consider adopting these thin-film photonic platforms as host materials for REIs.

Quantum Optical Storage in Atomic Ensembles.
A quantum optical memory should coherently map quantum coherence from an optical field to stationary excitations such as the spin of atoms. The mapping should be reversible, and on-demand, and the process should not add noise to the retrieved optical states. To achieve this, various protocols have been proposed and experimentally realized using atomic systems. As an example, gradient echo memory (GEM) offers controllable and efficient storage in an ensemble of atoms. In this case, a gradient of frequency broadening introduced by an external field ensures that different frequency components of the photon wavepacket are stored at different locations thus printing the phase information in spatial locations. Reversing the slope of the gradient in some sense reverses the phase evolution and leads re-emission of the photon wavepacket from the memory.
We work to implement quantum optical memories in solids and atomic gases using GEM and other echo protocols to allow arbitrary control (spectral, temporal, and spatial) of the stored information. Memories of this kind are the building blocks of future quantum communication networks.

Coherent Optical Sensing and Quantum Light Generation.
In our lab, we investigate atomic, optomechanical, and optical systems to develop exquisite sensors to measure EM fields, force, and temperature in various environments. In our recent work and in collaboration with Prof. Shakouri (Purdue University), we use intensity-squeezed states of light generated from a room-temperature atomic gas aiming to perform temperature sensing and thermal imaging of electronic structures beyond the capability of classical systems.

Cavity Quantum Electrodynamic Interactions.
The strength of interaction between photons and atoms is important for efficient and coherent control of quantum optical information. Interaction can be enhanced by optical resonators to overcome the probabilistic limit in quantum interactions. Such nonlinear interaction is key to deterministic entanglement creation between atomic and photonic qubits. Previously (at MIT), Prof. Hosseini investigated QED interaction of light with an ensemble of laser-cooled atoms inside a high-finesse cavity. Our group is now interested in realizing such interactions in solid-state media.
