Summary: Plasmonic nanolasers, which go beyond the diffraction limit, have gained significant attention. However, the high optical confinement caused by the plasmon effect also leads to metal absorption loss, increasing the pump threshold. This paper discusses the factors affecting the threshold, reviews experimental efforts, explores applications, and discusses approaches for threshold reduction and future possibilities.

Summary: Manipulating single emitter radiation is important for quantum information science. Coupling quantum emitters with microcavities and plasmonic antennas has been successful in enhancing radiation efficiency and directivity. However, generating complex radiation patterns such as vortex beams from a single emitter has been challenging. Here, researchers report a chiral plasmonic nanocavity that provides a strong local chiral vacuum field, enabling the generation of vortex beams through anomalous spontaneous emission. The scheme offers a new method for field manipulation in chiral quantum optics and nanoscale vortex lasers.

Summary: A giant enhancement of up to 34000 for out-of-plane (OP) exciton emission in indium selenide (InSe) is achieved via a designed plasmonic nanocavity consisting of a silver nanocube over a gold film. The large enhancement is attributed to the induced OP local electric field (Ez) within the nanocavity, which facilitates effective OP exciton-plasmon interaction. The nanoantenna effect resulting from the interaction also improves the directivity of spontaneous radiation, providing a potential avenue for designing on-chip photonic devices with an OP dipole orientation.

Summary: This work theoretically and systematically investigates the second harmonic generation (SHG) in a lithium niobate (LN) crystal by considering the transmission and reflection of TE-polarized pump light at the air-crystal interface. The physical process of light beam transport and nonlinear optical polarization generation in the crystal is described, and the reflection coefficient and transmission coefficient of pump light are derived. The conversion efficiency of the second-harmonic wave is found to depend on the transmission coefficient and other physical quantities, such as the length of the crystal and the amplitude of pump light, under the transmission and reflection models. The proposed analytical theory and formulation provide an accurate tool for evaluating the SHG energy conversion efficiency in practical situations and can be applied to other nonlinear optics problems.

Summary: The conductive polymer polyaniline (PANI) has been widely studied in the field of electrochromic energy storage devices (EESDs) for its rich color changes and good pseudocapacitive properties. A PANI and MnO2 nanocomposite structure with a coral-like nano-porous architecture was synthesized using a one-step electrodeposition approach. The rough coral-like structure provides a large quantity of nano porous ion transport channels, significantly improving the working voltage range and cycling stability of the electrode. A complementary full EESD was also constructed, allowing real-time observation of the EESD operating state based on color change. It exhibited stable performance under a large voltage window with good bistable performance and fast response speed.

Summary: This study presents a new on-chip diagnostic tool, T-FROG, for real-time full characterization of waveguided ultrashort optical pulses. Implemented on a thin-film lithium niobate platform, T-FROG accurately characterizes various properties of waveguided femtosecond pulses. In contrast to traditional techniques, T-FROG provides significant improvement by directly capturing temporal amplitude and phase profiles of ultrafast optical pulses inside photonic integrated circuits. The real-time in situ characteristics and dynamics of optical pulses offered by T-FROG show promise for their potential applications in the design, testing, and optimization of ultrafast photonic integrated circuits.

Summary: This paper presents the discovery of a unique unidirectionally rotating windmill scattering phenomenon by a magnetized gyromagnetic cylinder. The mechanism originates from the nonreciprocal unidirectional rotation of polarized magnetic charges on the surface of the cylinder, resulting in unidirectional scattering. The study also discusses the size dependence of this scattering phenomenon. These findings are important for investigating the interaction between electromagnetic waves and gyromagnetic materials or structures, as well as understanding topological photonic states in gyromagnetic systems from the perspective of classical electrodynamics and electromagnetics.
