Summary: Eighteen isotypic, lithium-containing rare-earth sulfides with the La3CuSiS7-structure type have been synthesized and characterized. These compounds are semiconductors with wide optical bandgaps in the visible region. They exhibit high thermal stability and potentially broad regions of optical transparency in the infrared regime. Two of these compounds, Ce3LiGeS7 and Ce3LiSnS7, show significant second-harmonic generation responses and high laser-induced damage threshold values.

Summary: Large-scale kainic acid single crystals were synthesized and studied for their linear and nonlinear optical properties. The non-centrosymmetric zwitterionic crystallization, molecular structure, and inter-molecular arrangement enhance the second-order optical nonlinearity of the crystal. The crystals exhibit good transparency in a broad spectral range and show enhanced second-harmonic generation and broadband THz generation.

Summary: Second harmonic dipoles generated in a nonlinear photonic crystal slab can be completely nonradiative, resulting in no energy transfer from the fundamental frequency to the second harmonic even when the phase-matching condition is satisfied - a phenomenon known as resonance-forbidden second-harmonic generation. Through numerical simulation, two mechanisms for achieving this phenomenon have been identified: symmetry protection and parameter tuning. The finite-size effect and the topological origin of this phenomenon are also discussed.

Summary: This Letter reports the fabrication of lithium niobate-on-insulator ridge waveguides with generalized quasiperiodic poled superlattices using electric field polarization technique and microfabrication techniques. The efficient second-harmonic and cascaded third-harmonic signals were observed in the same device, with normalized conversion efficiency of 1735% W-1 cm-2 and 0.41% W-2 cm-4, respectively. This work opens a new direction for nonlinear integrated photonics based on lithium niobate thin film.

Summary: Understanding symmetry breaking in ferroelectric materials is crucial for manipulating their functional properties. We developed a spectral imaging method using optical second harmonic generation to investigate the mechanisms behind crystallographic symmetry breaking. By studying (K,Na)NbO3 single crystals, we demonstrated the method's ability to analyze domain variants and their thermal evolution across phase transitions. The method can be extended to other ferroelectric materials with potential enhancements.

Summary: A new chiral trithiocyanate compound, K-4(HC3N3S3)(2)·H2O, is reported to have strong second-harmonic generation and high birefringence in comparison with the commercial NLO crystal beta-BaB2O4. The enhanced optical properties of K-4(HC3N3S3)(2)·H2O are attributed to the highly pi-conjugated [HC3N3S3](2-) rings.

Summary: This article demonstrates the nonlinear optical effects based on topological resonators, achieving second-harmonic generation (SHG) through the nonlinear interactions between two different types of topological corner modes. These corner modes possess ultrahigh Q factors and large modal overlap factor, simultaneously satisfying the doubly resonant condition for efficient SHG. These findings extend our understanding of nonlinear interactions between higher-order corner modes in a broader framework and have potential applications in topologically-protected imaging and sensing.

Summary: We experimentally study the tunability of second harmonic generation (SHG) in a 2D material/dielectric film/substrate layered structure. The tunability arises from two interferences: one between the incident fundamental light and its reflected light, and the other between the upward SH light and the reflected downward SH light. We demonstrate variations of three orders of magnitude in the SHG signals from a monolayer MoS2/TiO2/Ag layered structure.

Summary: In this study, second harmonic generation (SHG) and third harmonic generation (THG) in quantum dots with cylindrical geometry were investigated by solving the Schroedinger equation within the effective mass approximation. Results show that peaks of SHG and THG coefficients in different cylindrical quantum dot shapes occur at different photon energies, with peak energy increasing in the order of solid cylinders, convex cones, linear cones, and concave cones. The study also discussed potential applications and differences in energy separation for conical quantum dots compared to solid cylindrical quantum dots.

Summary: This study reveals that in inversion-symmetric semiconductor materials, second harmonic generation (SHG) is attributed to surface dipole effects or bulk-related electric quadrupole or magnetic dipole effects after the disappearance of SHG from dipoles within the bulk. The results show that by incorporating the contribution from spatial dispersion, certain unexplained rotational anisotropy SHG intensity features for different incoming light wavelengths or optical penetration depths can be well reproduced.

Summary: In this work, the optical properties of a tuned quantum dot/ring system with consideration of the electron-phonon interaction were theoretically investigated, particularly focusing on the second harmonic generation (SHG) and third harmonic generation (THG) under the e-p effect. The study revealed that the e-p interaction significantly influences the SHG and THG of the system, with the surface optical (SO) phonons having a greater impact on the optical properties compared to the longitudinal optical (LO) phonons. Additionally, the combined effect of LO and SO phonons resulted in the largest influence on the optical properties.

Summary: This study demonstrates the nonlinear manipulation of optical orbital angular momentum (OAM) spectra. By utilizing a nonlinear crystal for simultaneous second- and third-harmonic generation, the manipulation of fundamental waves with different OAM spectra is achieved, including customized OAM spectra for the second and third harmonics. The experimental results validate the theoretical predictions, and this approach holds potential applications in classical optics for multiplexing and in quantum optics for high-dimensional information processing.

Summary: This study demonstrates the enhancement of second harmonic generation (SHG) from multilayer structures of gallium selenide (GaSe) flakes integrated with Fabry-Perot structures using hybrid-genetic optimization (HGA). The HGA technique significantly speeds up the design process and achieves 128-fold and 400-fold SHG enhancement in single and double GaSe structures, respectively, compared to a reference sample. The SHG conversion efficiencies obtained from the HGA structures are significantly higher than previous reports on 2D material integrated resonant metasurfaces or Bragg cavities.

Summary: This study presents a novel theoretical analysis using the simplified bond hyperpolarizability model (SBHM) to approach the nonlinear tensor and compares it with group theory (GT). The analysis is based on a light-matter interaction classical phenomenological framework, requiring fewer independent parameters in the tensor than GT. This approach may open the path for similar analysis in other complex semiconductor surfaces and structures in the future, with potential applications to nanoscale surface characterization and real-time surface deposition monitoring.

Summary: This study investigated the potential of Brucea javanica in treating hypertension using network pharmacology and computational simulations. Two compounds from Brucea javanica were identified as potential inhibitors for peroxisome proliferator-activated receptor gamma (PPARG), a protein strongly associated with hypertension. Molecular dynamics simulations confirmed the stability of the ligand-receptor complex and the strong binding of the ligands to the catalytic site of PPARG. These findings suggest the potential of these compounds as promising drugs for hypertension.

Summary: We successfully demonstrate the growth of gallium phosphide (GaP) segments within indium phosphide (InP) nanowires, forming GaP/InP heterostructure nanowires. The GaP segments show visible wavelength photoluminescence (PL) during growth, while the InP nanowires emit infrared light. PL mapping and polarization analysis reveal that the emission mainly comes from the GaP segments. The experimentally obtained band gap values are verified with band structure calculations. This study contributes to the tuning of emission and optical properties of GaP/InP nanowires for future applications in information and communication technology.

Moreover, the study explores the effect of the incoming light polarization on the SHG intensity peak and the number of peaks. The research also highlights the contribution of spatial dispersion to the total SHG intensity. The findings provide insights into the nonlinear properties and photovoltaic performance of ABO(3) structures.
