A distinguishing feature of these MCIs is the formation of spectrally dependent concentric rings, governed by the refractive index distribution and dimensions of the hemispherical structures. In this work, we unveil a novel Moiré fringe pattern generated by superposing multiple concentric rings under polychromatic illumination of the MCIs. By capturing the spatial variations in these ring patterns with an inexpensive black-and-white CMOS camera, and analyzing the reflected spectrum, a machine learning algorithm is trained to recognize and reconstruct unknown incident spectra. The Moiré effect enhances the reconstruction of polychromatic spectra, as minute changes to the spatial composition of any superposing ring pattern are magnified in the resulting fringe. We demonstrate the development of an MCI-based smart spectrometer capable of achieving a spectral accuracy of 0.2 nm, high spectral resolution of 1.5 nm, and 450 nm bandwidth that spans the visible and near-infrared regime. This performance represents a significant improvement over similar devices and systems, and offers a cost-effective, compact solution for applications requiring precise spectral measurements, including portable sensing, elemental analysis, and advanced materials characterization.","PeriodicalId":13094,"journal":{"name":"IEEE Journal of Selected Topics in Quantum Electronics","volume":"32 3: Nanophotonics, Metamaterials and Plasmonics","pages":"5400111-5400111"},"PeriodicalIF":4.5,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148442263","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Chirality is a geometric property that refers to an object’s asymmetry and inability to be superimposed with its mirror image. The weak nature of chirality in molecules typically requires long light paths and high concentrations for detection. Metasurfaces can produce highly localized chiral fields, enhancing light-molecule interactions near their surfaces. This study demonstrates a dielectric metasurface based on symmetrically gapped silicon dimers for terahertz chiral sensing, which avoids introducing background chiral signals. The metasurface supports accessible superchiral hotspots in the dimer gap under both circularly and linearly polarized terahertz excitations. The bare metasurface achieves a volume-average terahertz circular dichroism (TCD) <italic>CE_av of 190 under circularly polarized light (CPL) and 200 under linearly polarized light (LPL). Notably, when a 5-μm-thick chiral biolayer is applied to the metasurface, a volume-averaged <italic>CE_av_bio of 85 (CPL) and 105 (LPL) is achieved. These findings are significant for advancing TCD spectroscopy in the terahertz range.","PeriodicalId":13094,"journal":{"name":"IEEE Journal of Selected Topics in Quantum Electronics","volume":"32 3: Nanophotonics, Metamaterials and Plasmonics","pages":"1-8"},"PeriodicalIF":5.1,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147557878","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Silicon nitride platform stands out as a promising candidate for on-chip supercontinuum generation due to high nonlinearity, broad transparency window, CMOS compatibility, and negligible two-photon absorption in the near-infrared. However, the performance of conventional etched silicon nitride-on-insulator waveguides is still constrained by the strong mid-infrared absorption of the silica cladding, which limits the efficiency and bandwidth of supercontinuum generation. Here, we designed a broadband mid-infrared supercontinuum of bound states in the continuum zeroth-order transverse magnetic modes based on etchless waveguides with silicon-nitride-on-insulator wafers. The dispersion engineering of the bound states in the continuum modes was successfully achieved with precise control of cladding structural parameters, resulting in an expanded anomalous dispersion region spanning from 1.15 μm to 2.69 μm. Moreover, a mid-infrared supercontinuum source with 3.3-octave-spanning bandwidth was developed, covering a spectral range of 0.5-5 μm. The study is expected to accelerate the applications of mid-infrared photonic integration in environmental monitoring, biomedical diagnostics, and spectroscopy.","PeriodicalId":13094,"journal":{"name":"IEEE Journal of Selected Topics in Quantum Electronics","volume":"32 3: Nanophotonics, Metamaterials and Plasmonics","pages":"1-7"},"PeriodicalIF":4.5,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148480807","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, low-threshold room-temperature operation remains fundamentally limited in plasmonic systems due to competing metallic absorption, radiative leakage, and lateral diffraction losses within the cavity. Compared with conventional dye-based gain media, the multiple quantum well (MQW) platform offers improved material stability and reproducibility. Here we demonstrate room-temperature SLR lasing at 930 nm by integrating a dielectric multiple-quantum-well gain medium with periodic metallic nanoparticle arrays. Rather than relying solely on Q-factor analysis, we establish that modal selection and threshold behavior are governed by geometry-dependent redistribution of dissipation channels. By systematically varying the metal filling factor, lattice constant, and nanoparticle geometry including circular, square, and rectangular shapes, we reveal that different lattice symmetries modify lateral coupling coefficients and lift modal degeneracy, thereby reshaping the balance among metallic absorption, radiative feedback, and lateral leakage. Among the investigated configurations, the square geometry with a filling factor of 10% achieves the lowest threshold of 0.059 MW/cm2 and a linewidth of 1 nm. Our results demonstrate that gain-loss engineering through κ-mediated lateral coupling control provides an effective strategy to regulate modal dissociation and minimize effective cavity loss in plasmonic SLR lasers.","PeriodicalId":13094,"journal":{"name":"IEEE Journal of Selected Topics in Quantum Electronics","volume":"32 3: Nanophotonics, Metamaterials and Plasmonics","pages":"1500807-1500807"},"PeriodicalIF":4.5,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148627333","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, research on wave manipulation devices capable of simultaneously achieving both functionalities remains limited, despite their great potential for system miniaturization and functional integration. In this study, we design and realize a broadband device capable of simultaneously steering and compressing the TM-polarized EM waves using subwavelength protrusion metallic tunnels. The underlying physical mechanisms are quantitatively explained through wave optics and optical surface transformation, indicating the size ratio between the incident and output surface governs both the steering angle and the compression ratio. Numerical simulations demonstrate that under a steering angle of 40° and a compression ratio of 0.4, the averaged energy transmittance across 3-12 GHz is above 0.8. The experiments further validate its effectiveness by measuring the magnetic field distributions of the output beam at various frequencies. The excellent beam steering and compressing effects make the proposed device highly promising for next-generation multifunctional wave manipulation in advanced communication systems.","PeriodicalId":13094,"journal":{"name":"IEEE Journal of Selected Topics in Quantum Electronics","volume":"32 3: Nanophotonics, Metamaterials and Plasmonics","pages":"1-8"},"PeriodicalIF":5.1,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147558088","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
