Aspects of nonlocality in atom-photon interactions in a cavity [PDF]

, 2000
We investigate a Bell-type inequality for probabilities of detected atoms formulated using atom-photon interactions in a cavity. We consider decoherence brought about by both atomic decay, as well as cavity photon loss, and study its quantitative action ...

Micromanipulation of InP lasers with optoelectronic tweezers for integration on a photonic platform [PDF]

, 2016
The integration of light sources on a photonic platform is a key aspect of the fabrication of self-contained photonic circuits with a small footprint that does not have a definitive solution yet.

Effect of dissipative forces on the theory of a single-atom microlaser [PDF]

, 1998
We describe a one-atom microlaser involving Poissonian input of atoms with a fixed flight time through an optical resonator. The influence of the cavity reservoir during the interactions of successive individual atoms with the cavity field is included in

Laser patterning of large-scale perovskite single-crystal-based arrays for single-mode laser displays

International Journal of Extreme Manufacturing, 2023
Lead halide perovskites have attracted considerable attention as potential candidates for high-performance nano/microlasers, owing to their outstanding optical properties. However, the further development of perovskite microlaser arrays (especially based

Laser particles with omnidirectional emission for cell tracking

Light: Science & Applications, 2021
The ability to track individual cells in space over time is crucial to analyzing heterogeneous cell populations. Recently, microlaser particles have emerged as unique optical probes for massively multiplexed single-cell tagging.

Impact of Cavity Geometry on Microlaser Dynamics

Physical Review Letters, 2023
We experimentally investigate spatio-temporal lasing dynamics in semiconductor microcavities with various geometries, featuring integrable or chaotic ray dynamics. The classical ray dynamics directly impacts the lasing dynamics, which is primarily determined by the local directionality of long-lived ray trajectories.

Möbius strip microlasers [PDF]

2021 Conference on Lasers and Electro-Optics Europe & European Quantum Electronics Conference (CLEO/Europe-EQEC), 2021
Direct laser writing [1] enables the fabrication of almost arbitrary three-dimensional (3d) microstructures with feature sizes of less than 1 µ m and allows to create 3d organic microlasers such as pyramids with high quality and low surface roughness [2] .

Quantum trajectory analysis of a thresholdlike transition in the microlaser [PDF]

, 1997
In a recent microlaser experiment [K. An et al., Phys. Rev. Lett. 73, 3375 (1994)], a thresholdlike transition of intracavity mean photon number as a function of intracavity mean atom number has been observed.
