Summary: This study proposes the concept of nanoscopic electron reservoir (NER) for direct electro plasmonic and electro-optic modulation. By exploiting the nonclassical effects of conduction electrons, highly electrically susceptible NERs are constructed and achieve pronounced direct electrical tuning of the plasmon mode. Moreover, the electro-plasmonic tuning can be efficiently translated into modulation of optical scattering.

Summary: Electro-optic modulation, an important topic in the field of communications and sensing, faces limitations in increasing modulation efficiency due to the monotonic mapping relationship between electrical and optical signals. To overcome this limitation, researchers reveal a new mechanism called phase-transition EO modulation, achieved through the reciprocal transition between distinct phase planes. An integrated mode-locked laser prototype is implemented, achieving an ultrahigh modulation energy efficiency and a high contrast ratio, with applications in radio-over-fiber communication and acoustic sensing. This advancement in EO modulation technology opens up new possibilities for green communication and ubiquitous sensing.

Summary: The promising applications of photonics rely on the fabrication of high-quality metal thin films with controlled thickness in the range of a few nanometers. These materials exhibit highly nonlinear response to optical fields due to ultrafast electron dynamics. However, the understanding of this phenomenon on such small length scales is limited. In this study, a new mechanism controlling the nonlinear optical response of thin metallic films is revealed, which is dominated by ultrafast electronic heat transport when the film thickness is sufficiently small. By experimentally and theoretically studying electronic transport in these materials, the researchers explained the observed temporal evolution of photoluminescence in two-pulse correlation measurements. They found that ultrafast thermal dynamics plays a crucial role in determining the strength and time-dependent characteristics of the nonlinear photoluminescence signal. Their findings provide new insights into the nonlinear optical response of nanoscale materials and offer possibilities for controlling and utilizing hot carrier distributions in metallic films.

Summary: An optical phased array (OPA) is a non-mechanical beam steering technique that shows great potential in various applications. This study focuses on reducing sidelobe levels in both the azimuthal and polar directions in an OPA. To achieve this, a Y-splitter-assisted cascaded coupling scheme and an apodized grating emitter are proposed for Gaussian power distribution in the azimuthal and polar directions, respectively. Experimental results show significant improvement in sidelobe suppression ratio (SLSR) and field of view for a 120-channel OPA.

Summary: By using specially designed anisotropic nanodimers, we achieved nonradiative coupling between a quantum emitter and a surface plasmon polariton, allowing the generation of single photons with spin and orbital angular momenta encoded. We demonstrated the on-chip generation of well-collimated, circularly polarized, and high purity single-mode vortex beams with different topological charges and high single-photon purity. This approach can be extended to produce multiple single-photon radiation channels with different polarizations, enabling advanced quantum photonic technologies.

Summary: Impurity-vacancy centers in diamond provide a class of robust photon sources with versatile quantum properties. The ensembles of color centers have tunable photon-emission statistics and their emission properties can be controlled by different types of excitation. Electron-beam excitation can synchronize the emitters' excitation and control the second-order correlation function g(2)(0), as confirmed by experimental results in this letter. Such a photon source based on an ensemble of few color centers in a diamond crystal offers a highly tunable platform for room temperature informational technologies.

Summary: We propose an efficient approach for actively controlling the Rabi oscillations in nanophotonic emitter-cavity analogs based on the presence of an element with optical gain. Inspired by recent developments in parity-time (PT)-symmetry photonics, we show that nano-or microcavities where intrinsic losses are partially or fully compensated by an externally controllable amount of gain offer unique capabilities for manipulating the dynamics of extended (collective) excitonic emitter systems. Furthermore, we show that there is a specific gain value that leads to an exceptional point, where both the emitter and cavity occupation oscillate practically in phase, with occupation numbers that can significantly exceed unity.

Summary: The paper discusses the impact of an extended model proposed by Halevi on the nonlocal response of plasmonic materials and nanostructures. It reevaluates the Mie scattering coefficients for a cylinder and corresponding plasmon-polariton resonances within this framework. The analysis reveals a nonlocal, collisional, and size-dependent damping term that affects the resonances in the extinction spectrum. The implementation of the Halevi model in the time domain is particularly important for efficient and accurate modeling of nanogap structures and other nanoscale features in nanoplasmonics applications.
