The multiplicity of degrees of freedom endows them with the artificial manipulation of molecular patterns, yielding compelling scenarios toward on-demand harnessing for applied stimuli, in which the molecular phase gradually reveals its remarkable controllability. Here, we report a quaternary encoding scheme relying upon gain-dominated phase customization. Initially, via artificial modulation of laser gain, the deterministic harnessing of the type and velocity of molecular phase evolution is well implemented, in which one phase-oscillating state, one stationary state, and two phase-sliding states with different evolving velocities can be reliably switched to each another. Moreover, taking the four states in different phase regions as the encoding symbols, the hybrid quaternary encoding format is implemented. Due to the distinct characteristics of each phase region, this scheme can facilitate the recognition of the code symbols, therefore possessing high fidelity and high antijamming capability. Particularly, incorporating both type and velocity of molecular phase as characteristics of the code elements endows the hybrid encoding scheme with the potential for dimensional scalability. All of these results experimentally demonstrate the encoding capabilities of relative phase as well as highlight their potential applications in large-capacity all-optical storage and soliton communication.","PeriodicalId":23,"journal":{"name":"ACS Photonics","volume":"66 1","pages":""},"PeriodicalIF":7.0,"publicationDate":"2025-02-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143507198","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we investigate the temperature-dependent spectral properties of a single defect in hBN to understand the dominant dephasing mechanisms due to phonons. We observe a sharp zero-phonon line (ZPL) emission accompanied by Stokes and anti-Stokes optical phonon sidebands assisted by the Raman-active low-energy (≈ 6.5 meV) interlayer shear mode of hBN. The shape of the spectral lines around the ZPL is measured down to 78 K, at which the line width of the ZPL is measured as 211 μeV. Using a quadratic electron–phonon interaction, the temperature-dependent broadening and the lineshift of the ZPL are found to follow a temperature dependence of T + T5 and T + T3, respectively. Furthermore, the temperature-dependent line shape around the ZPL at low-temperature conditions is modeled with a linear electron–phonon coupling theory, which results in a 0 K Debye–Waller factor of the ZPL emission as 0.59. Our results provide insights into the underlying mechanisms of electron–phonon coupling in hBN, which is critical to enhance their potential for applications in quantum technologies.","PeriodicalId":23,"journal":{"name":"ACS Photonics","volume":"210 1","pages":""},"PeriodicalIF":7.0,"publicationDate":"2025-02-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143507205","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Thin films serve as a promising material platform for the integration, yet fabrication without compromising the properties of the materials and rare-earth ions remains challenging. In this work, we fabricate micrometer-thin yttrium aluminum garnet (YAG) films from bulk crystals using ion implantation techniques. The resulting films preserve the single-crystalline structure of the original bulk crystal. Notably, the embedded rare-earth ions are photostable and exhibit bulk-like spin coherence properties.

Optical methodologies in force sensing, despite offering exceptional sensitivity and swift responsiveness, often necessitate the alignment of external optics, hindering the pursuit of high-density integration and downscaling. In this work, a compact optical tactile sensor incorporating a GaN device with a deformable reflective dome is introduced. The device adopts a monolithic integration approach comprising a light emitter and four photodetectors. The PDMS dome, embedded with calcium carbonate powder, functions as a light modulator, effectively converting tactile signals into optical signals. The developed sensor exhibits a compact footprint of 4 × 4 mm2 and a measurement range from 0 to 1.1 N with a high resolution of 1.5 mN. Additionally, an encoding system is implemented to recognize the orientation of the applied force and wirelessly transmit the results to a user interface, revealing the potential use of the proposed optical tactile sensor in practical applications.","PeriodicalId":23,"journal":{"name":"ACS Photonics","volume":"32 1","pages":""},"PeriodicalIF":7.0,"publicationDate":"2025-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143495853","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Quite recently, the concept has been introduced in the near-field regime to tune the radiative heat transfer between two nonequilibrium objects but with no experiment reported yet. In this work, we perform a deep investigation about this subtle physical effect between uniaxial polar crystals (calcite, α-sapphire, and α-quartz) possessing strong anisotropic photonic dispersions in the thermal infrared bands both theoretically and experimentally. Super Planckian emission was explicitly observed under the excitation of surface phonon polaritons (SPhPs). Utilizing these localized modes, particularly the hyperbolic photonic surface modes, we demonstrated that the couplings and tunneling possibility of evanescent photons could be largely modulated by twisting the in-plane optical axis (OA) of one of the crystals. In the context of near-field interaction, a prominent heat flux modulation with a ratio exceeding 16% was obtained between the sapphire pair with great experiment–theory agreement.

Two prominent non-computational modalities include bright field and phase contrast microscopy that can create contrast in an image related to the amplitude and phase features of a sample, respectively. Often, the size and cost of the equipment typically required for these applications, such as bulky microscopes, can limit their availability to well-equipped laboratories. Furthermore, capturing both of the phase contrast and bright field images on the same camera in a microscope typically requires interchanging optical components. Metasurfaces are ultra-thin nanostructures that can merge both of these operations into a single miniaturized device in the push toward shrinking the size of imaging systems. Here, a silicon-based metasurface that supports a Mie resonance is demonstrated to perform non-computational, near-infrared phase contrast and bright field multimodal microscopy that can be tuned by changing the polarization of the illumination. We performed experiments using optical fields with phase variations synthesized by a spatial light modulator and introduced by propagation through semi-transparent samples, including C. elegans, unstained human prostate cancer cells, and breast tissue. The results demonstrate the potential of metasurfaces to be used in miniaturized optical systems for label-free point-of-care testing beyond the laboratory.","PeriodicalId":23,"journal":{"name":"ACS Photonics","volume":"108 1","pages":""},"PeriodicalIF":7.0,"publicationDate":"2025-02-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143477380","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The requirement for negligible insertion loss in low-power-consumption thermo-optic phase shifters is becoming increasingly critical, particularly in cascaded configurations employed in applications such as LiDAR, photonic computing, programmable photonics, and quantum photonics. To address this need, we present a comprehensive theory based on the fundamental coupled-mode theory for sharp-bent waveguides. We employ phase mismatch in a compact spiral waveguide to eliminate coupling loss and enhance the efficiency of thermo-optic phase shifters. Our approach successfully overcomes inherent trade-offs, demonstrating ultralow insertion loss in compact and power-efficient silicon-based phase shifters operating in the C-band. The proposed simplest-design device exhibits a record lowest measured insertion loss of 0.14 dB among all residual-heat-absorption-type phase shifters. Simultaneously, the power consumption and modulation bandwidth are measured to be 3.4 mW/π and 12.5 kHz, respectively. This methodology holds substantial promise for minimizing the insertion loss across various residual-heat-absorption-type thermo-optic phase shifters, which employ different materials and operate in diverse bands, such as the telecom and visible spectra. The experimental realization of the C-band silicon phase shifter on IMEC’s Si/SiN platform expresses its potential as a fundamental component for scalable mass production in extensive photonic circuit architectures.","PeriodicalId":23,"journal":{"name":"ACS Photonics","volume":"13 1","pages":""},"PeriodicalIF":7.0,"publicationDate":"2025-02-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143470958","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
