Rather than a comprehensive review, we aim to share insights on the often demanding yet rewarding path of CPL research. We first highlight key questions for newcomers, then organize selected sections by molecular structure, with emphasis on our own contributions. Central to the discussion is the dissymmetry factor (glum), governed by the interplay between electric and magnetic dipole transition moments, though other descriptors are also considered. Strategies in organic and inorganic molecular design leading to enhanced CPL efficiency are discussed, together with a critical evaluation of potential applications, particularly in sensing. In this context, NIR-emitting CPL fluorophores emerge as highly promising. The integration of CPL-active molecules in solid-state devices, as well as links to other chiral-related phenomena such as chiral-induced spin selectivity, are also addressed. Looking ahead, theoretical models and artificial intelligence are considered valuable tools to complement advanced experimental approaches, helping to overcome current limitations and to unlock new opportunities in both fundamental studies and technological applications. We conclude with our own reflections, practical advice, and perspectives for future research.","PeriodicalId":116,"journal":{"name":"Advanced Optical Materials","volume":"14 11","pages":""},"PeriodicalIF":7.2,"publicationDate":"2026-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/adom.202503285","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147569703","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The room temperature phosphorescence (RTP) emission color shifts from blue to green to yellow as excitation wavelength increases. CDs@Al2O3 synthesized at an optimized calcination temperature of 500°C exhibits lifetimes of up to 1.36 s under 258 nm excitation and 0.63 s at 520 nm.

In such networks, distinct groups of nodes and links can be decomposed into different types of multipartite networks, whose nodes are partitioned into disjoint sets with edges permitted only across these sets. In optics, this decomposition motivates a network-based analysis of multiphase optical materials by introducing multipartite networks to model intra- and inter-phase electromagnetic interactions. Here, we develop heterogeneous network modeling of wave scattering to engineer multiphase random heterogeneous materials. We devise multipartite network decomposition determined by material phases, which is examined using uni- and bi-partite network examples for two-phase multiparticle systems embedded in a host medium. We show that the directionality of the bipartite network governs the phase-sensitive alteration of microstructures. The proposed modeling enables a network-based design to achieve phase-sensitive microstructural features, while almost preserving the overall scattering response. With examples of designing quasi-isoscattering stealthy hyperuniform materials, our results provide a recipe for engineering multiphase materials for wave functionalities.","PeriodicalId":116,"journal":{"name":"Advanced Optical Materials","volume":"14 11","pages":""},"PeriodicalIF":7.2,"publicationDate":"2026-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/adom.202503499","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147568669","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In recent years, there is a growing trend in using USPL in the field of welding. This emerging welding technology is primarily applied to the welding of transparent materials. By focusing USPL at the welding interface, laser energy transfers to substrates within a narrow area through the nonlinear absorption process, accompanied with large amount of heat release to achieve the melting and bonding. Due to the extremely short pulse width and limited energy input, thermal diffusion around the joint is minimal, resulting in the diminished welding region, lower thermal stress, and enhanced welding precision. This method holds significant promise for welding samples with a large coefficient of thermal expansion (CTE) difference. In this review, the welding of transparent materials is first introduced, including the welding process, mechanism, and process optimization. Following this, the welding of transparent materials-opaque materials and opaque materials-opaque materials are described. The current progress in the applications of USPL welding is then presented.

The fibers are fabricated using a post-feeding melt-in-tube method by precisely controlling the interfacial reaction time (<10 min), which effectively resulted in Er:YAG nanocrystals embedded in the core region. Spectroscopic studies reveal that the nanocrystal size effect modifies the energy level splitting of erbium ions, leading to an extended emission bandwidth. When deployed in a ring-cavity laser, a 30-cm-length fiber enables a low fusion splicing loss of 0.1 dB with standard single-mode silica fibers and continuous tuning over 126 nm (1494–1620 nm) with an optical signal-to-noise ratio of ∼70 dB, making it suitable for S+C+L band tunable laser applications.
