Summary: In this study, we examined the geometrical properties of light propagation in a hypothetical nonlinear medium using a fully covariant electromagnetic theory in (2 + 1)-dimensions. By defining the local and nonlinear constitutive relations, we derived the phase velocity and polarization of the waves, and analyzed three specific cases in detail. Our results show that this version of electromagnetism in low dimensions can exhibit phenomena such as one-way propagation and controlled opacity, among others, for a wide range of dielectric and magneto-electric parameters.

Summary: The investigation on the nonlinear optical properties of two typical two-dimensional metal-organic frameworks (2D MOFs) showed that 2D Cu-MOF exhibits a large nonlinear optical coefficient, while 2D Zn-MOF does not show any nonlinear optical effect. The Cu center of Cu-MOF with variable valence electrons and vacant 3d atom orbit enhances the nonlinear optical effect, while the Zn ion of Zn-MOF with fixed valence electrons and fully occupied d orbit makes it hard to produce observable nonlinear optical effect. Furthermore, the ability of 2D Cu-MOF in all-optical spatial light modulation and optical switch based on the principle of SXPM was demonstrated, shedding light on the physics of 2D MOFs in all-optical light modulation.

Summary: This study presents a novel nonlinear two-dimensional (2D) warped discrete Fourier transform (WDFT) amplitude demodulation method for higher-resolution measurements. The method is applied to the nonlinear 2D amplitude demodulation of fringe-wave fields acquired by a deformed Mach-Zehnder interferometer. Experimental validation demonstrates the efficiency of the proposed algorithm for amplitude demodulation with dense sampling points in the central part of the envelope.

Summary: In this study, nonlinear optical effects in electron systems with and without inversion symmetry in a Fabry-Perot cavity are investigated. The coupling of a noninteracting lattice model to two modes of the quantized light field is used to model general photon up- and down-conversion processes. Truncated models are shown to capture correlation effects induced by photons in the electronic subsystem despite their small Hilbert space.

Summary: The researchers reported the first NLO-active mercuric nitrates, KHNO and RHNO, which are assembled through ionic polarization and exhibit strong second-harmonic generation. These compounds possess characteristics suitable for UV NLO materials, such as simple solution preparation, centimeter-scale crystal size, and sufficient birefringence. Theoretical calculations and single-crystal structure analysis revealed the crucial role of the highly condensed and distorted [Hg(NO3)4] module, with Hg2+ cation quadruply bidentate nitrate-ligated, in the significant SHG responses. This work highlights the potential importance of modules with multiple bidentate ligands for high-performing next-generation NLO materials.

Summary: Two new borate-based compounds Na6Mg3B10O18F6 and K3NaB10O16F2 were discovered, with [B5O11] and [B5O10F] as their fundamental building blocks, respectively. The calculated results showed that K3NaB10O16F2 has a larger band gap and birefringence compared to Na6Mg3B10O18F6. The introduction of [B-O/F] units was found to improve the band gap and birefringence, as analyzed by the charge-transfer model and response electron distribution anisotropy method. These findings will contribute to the exploration of deep-ultraviolet birefringent optical materials.

Summary: A fluorine-enriched-induced centrosymmetric-to-noncentrosymmetric transformation strategy is employed to discover a new noncentrosymmetric cerium fluoride sulfate, Ce3F4(SO4)(4), with phase-matchable second-harmonic generation (SHG) effect and sufficient experimental birefringence. The ordered arrangement of fluorinated cerium-centered polyhedra and SO4 tetrahedra plays a significant role in the SHG activity and birefringence. The study demonstrates that introducing metal-centered polyhedra with a high degree of fluorination is a valuable method for designing novel nonlinear optical materials.

Summary: Due to their large band gap, tetrahedron-based compounds have gained increasing attention in the development of deep-ultraviolet nonlinear optical crystals. This study designs and obtains the Li2NH4Rb(SO4)(2) crystal, which exhibits a strong second-harmonic generation (SHG) response, a large band gap, and favorable growth habit to large crystals. The coordination of the optimized structure and disordered cations in this crystal results in the strong SHG response, making it a typical tetrahedron-based deep-ultraviolet nonlinear optical example.

Summary: Covalent functionalization of few-layer TiS2 with tetraphenylporphyrin (TPP) diazonium salts is achieved for the first time. The excited-state behavior of the newly synthesized TPP-TiS2 nanohybrid is investigated, revealing enhanced saturation absorption performance compared to pure TiS2. The reinforced band-filling effect due to intrahybrid energy transfer is believed to play a crucial role in the nonlinear absorption of TPP-TiS2.

Summary: A cobalt carbonate hydroxide core-shell nanowire was synthesized on carbon fiber paper through a wet-chemistry method for the hydrogen evolution reaction (HER) in water splitting. The CoCH@Co-MOF nanowire exhibited excellent catalytic activity with small overpotential, small Tafel slope, and large exchange current density. The one-dimensional morphology facilitated charge conduction, and the amorphous MOF framework endowed the nanowire with efficient catalytic activities.
