Ensemble emission of isolated organic chromophores incorporated into an organometallic single crystal

Nanophotonics, Volume 14, Issue 14, Page 2443-2451, July 2025.
Abstract Molecular quantum emitters are becoming increasingly important in quantum information and communication. As a stepping stone towards a single‐molecule quantum system, the collective emission from the ensemble of isolated organic chromophores, randomly and sparsely incorporated into an organometallic host crystal, is characterized by Raman and ...

Cooperative effects on Optical Forces- Dicke's Bullet

, 2001
We investigate the cooperative effects on optical forces in a system of N two level atoms occupying a volume of dimensions to within $\lambda ^3$, where lambda is radiation wavelength and is driven by a coherent radiation field with a spatial profile ...

Unified superradiant phase transitions [PDF]

Physical Review A, 2019
We prove, by means of a unified treatment, that the superradiant phase transitions of Dicke and classical oscillator limits of simple light-matter models are indeed of the same type. We show that the mean-field approximation is exact in both cases, and compute the structure and location of the transitions in parameter space.

Plasmon–exciton polaritonic emission lifetime dynamics under strong coupling

Nanophotonics, Volume 14, Issue 14, Page 2485-2493, July 2025.
Abstract In this study, we investigate the contribution of resonant and non‐resonant excitation conditions on the polariton decay dynamics of strongly coupled rhodamine 6G (R6G) and surface plasmon polariton (SPP). We showed proof of strong coupling between SPP and R6G exciton from the dispersion relations measured by total internal reflection ...

Superradiant scattering in fluids of light

, 2019
We theoretically investigate the scattering process of Bogoliubov excitations on a rotating photon-fluid. Using the language of Noether currents we demonstrate the occurrence of a resonant amplification phenomenon, which reduces to the standard ...

Local Tuning of the Epsilon‐Near‐Zero Condition in Hybrid Silicon Waveguides Using Reactive Laser Annealing

Advanced Photonics Research, Volume 6, Issue 6, June 2025.
This work demonstrates the use of reactive laser annealing to selectively tune the epsilon‐near‐zero condition of tin‐doped indium oxide patches integrated in silicon waveguides. This postgrowth annealing technique enables flexible control over the optical constants of transparent conducting oxides (TCOs) at critical telecom wavelengths, paving the way

Coherent spin relaxation in molecular magnets

, 2008
Numerical modelling of coherent spin relaxation in nanomagnets, formed by magnetic molecules of high spins, is accomplished. Such a coherent spin dynamics can be realized in the presence of a resonant electric circuit coupled to the magnet.

Ultra‐broadband and passive stabilization of ultrafast light sources by quantum light injection

Nanophotonics, Volume 14, Issue 11, Page 1857-1864, June 2025.
Abstract Nonlinear optical effects such as frequency conversion form the basis for many practical light sources. In a variety of settings, the performance of such sources is limited by quantum noise. In many nonlinear systems, this quantum noise gets strongly amplified, as a result of the large sensitivity of the nonlinear dynamics to changes in the ...
