Summary: The collection of single-photon emission from a quantum dot is demonstrated using a Bragg waveguide and a photonic wire bond in a cryogenic environment. The use of the photonic wire bond eliminates the need for in-cryostat alignment, offering a scalable integration of quantum photonic devices. The findings highlight the feasibility of using photonic wire bonds for single-photon collection at low temperatures.

Summary: We investigated the multiphoton blockade effects in a single-mode cavity interacting with two three-level atoms in A configuration with position-dependent atom-field coupling. We considered the dipole-dipole interaction (DDI) between the atoms and showed its strong influence on multiphoton blockade. The DDI induced an asymmetry in the emission spectra as a function of pump field detuning, leading to either photon antibunching or two-photon bunching depending on the detuning. Our findings are important for the experimental realization of similar systems with DDI.

Summary: In this study, a method is proposed to deterministically integrate single quantum dots with tailor-made photonic structures. A nondestructive luminescence picking method called nanoscale-focus pinspot (NFP) is used to reduce the luminous quantum dot density. The selected quantum dot is then deterministically integrated with a tailor-made photonic structure, leading to improved extraction efficiency.

Summary: This study investigates a scheme in which a single emitter, a semiconductor quantum dot, is embedded in a microcavity to generate single photons. By exploiting the splitting of the cavity mode, one for excitation and the other for collection, the best population inversion is achieved with a detuned laser pulse. The Rabi oscillations exhibit an unusual dependence on pulse power, attributed to the non-trivial effect of phonons on the exciton dynamics.

Summary: Light-matter interactions in optical cavities are crucial for integrated quantum photonics applications. Hexagonal boron nitride (hBN) has emerged as a promising van der Waals platform for quantum emitters, but progress has been hindered by the inability to simultaneously engineer an hBN emitter and a narrow-band photonic resonator. In this study, we overcome this challenge by demonstrating deterministic fabrication of hBN nanobeam photonic crystal cavities with high quality factors across a broad spectral range. We also create a monolithic cavity-emitter system tailored for a blue quantum emitter, induced deterministically through electron beam irradiation. This work presents a promising approach for scalable on-chip quantum photonics and opens up possibilities for quantum networks based on van der Waals materials.

Summary: This study demonstrates ultrafast absorption dynamics and enhanced features of photonic modes in a one-dimensional photonic crystal embedded with barium titanate (BaTiO3, BTO). The transient absorption behavior and nonlinear absorption dynamics reveal the excited-state absorption dynamics of BTO defect energies and the enormous cavity field confinement effect. The strong optical nonlinearities and enhanced features offer insights into electron-photon interaction, opening up possibilities for novel nonlinear, hybrid optoelectronic, and photonic device applications.

Summary: This study demonstrates the coupling of an InAs/GaAs quantum dot to a fabricated bullseye cavity with a high cooperativity, providing nearly degenerate and Gaussian polarization modes for efficient optical accessing. The researchers observed extremely short spontaneous emission lifetimes of the quantum dot and approximately 80% transparency of light reflected from the cavity. Utilizing induced transparency for photon switching and coherent control of the quantum dot spin could contribute to the establishment of quantum networks.

Summary: In this study, the coupling of a truncated Gaussian-shaped microcavity to a quantum dot (QD) was achieved using wet-chemical etching and epitaxial semiconductor overgrowth. Experimental results confirmed the agreement with simulations in terms of cavity modes and their spatial profiles. By tuning the temperature, transitions of a QD inside the cavity between resonance and off resonance were successfully achieved. The Purcell enhancement effect and the single-photon characteristic of the QD were preserved, as evidenced by a reduced decay time and second-order correlation measurements.

Summary: This paper theoretically explores the nonlinear optical response in a hybrid cavity quantum electrodynamic system, including optical bistability and four-wave mixing. The optical bistability is demonstrated by controlling a strong pump field driving a quantum dot. The modulation of the quantum dot's dressed state is achieved by altering the field parameters. The proposed system also generates a controllable four-wave mixing signal in the output probe field, which is significantly changed under the conditions of strong coupling and high pump power, resulting in the formation of an optomechanically induced transparency window and slow light. The investigation of this system has potential applications in on-chip quantum dot-based nanophotonic devices.

Summary: Based on the combined Dicke, Bose-Hubbard, and Lipkin-Meshkov-Glick Hamiltonian, this study investigates the formation of photonic rogue waves in the strongly dispersive regime. The study reveals the redistribution of photons and excited atoms in the whole array due to the interplay between photon hopping-induced tunneling effect and self-attractive nonlinearity, resulting in the occurrence of Peregrine soliton states in both photonic and atomic fields. The study also discovers an intensity clamping effect in which the sum of the peak intensities of rogue waves remains constant.
