Nevertheless, their direct amplification remains challenging owing to nonlinear phase accumulation, spatial mode distortion, and topological-charge-dependent spectral dispersion. Here, we demonstrate a high-average-power 2-μm femtosecond vortex laser system consisting of a mode-locked laser source and a multi-stage single-crystal fiber (SCF) amplifier, where the large mode area and efficient thermal management of the SCF enable high-fidelity amplification of femtosecond vortex beams with high efficiency and power-handling capability. An average output power of 40.2 W is achieved for the lowest-order topological charge ( l =1) optical vortex at 2.09 μm, corresponding to an amplification gain of >19 dB . Moreover, power scaling of higher-order ( l =3 and 5) femtosecond optical vortices is also demonstrated with both preserving the spatial properties associated with a clear central singularity and a spiral phase front. This work, providing the highest average power of femtosecond optical vortices in the 2-μm spectral range, proves a straightforward way for direct power scaling of structured laser beams with spatially irregular intensity distribution and ultrafast temporal characteristics.","PeriodicalId":20048,"journal":{"name":"Photonics Research","volume":"16 1","pages":"4466"},"PeriodicalIF":7.6,"publicationDate":"2026-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149089868","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}

Inspired by the distributed organization of mechanically responsive sensing units in aquatic crustaceans, we present a microstructured fiber tip Fabry–Perot optomechanical ultrasonic probe family whose resonant responses are systematically differentiated across distinct ultrasonic bands through geometrically tailored coupling between the diaphragm and supporting beams. In this architecture, the folded supporting beams act as a geometry-defined elastic boundary of the diaphragm and participate directly in the pressure-induced cavity length variation through coupled support translation and diaphragm bending. Finite-element modeling established a resonant design framework, and three probes fabricated by two-photon polymerization were designed with distinct resonant frequencies of 174 kHz, 1.0 MHz, and 1.6 MHz. The simulated resonances remained within the same first-order diaphragm-dominated modes. Experiments confirmed that the probes exhibited clearly differentiated response bands. The 1 MHz probe exhibited a sensitivity of 0.971 V/kPa, a noise-equivalent pressure of 1.04 Pa, and a photoacoustic bandwidth of 31.52 MHz under a 20% peak amplitude criterion, together with stable pulse detection and wide angular response. Representative demonstrations validated transient acoustic perception and multiband burst recognition, where decision-level fusion increased the mean detection rate from 30.4%–67.3% to 95.4%. Underwater ultrasonic imaging was also demonstrated. This work establishes a structurally differentiated lab-on-fiber optomechanical architecture for compact optical ultrasound detection and optoacoustic microsystems.","PeriodicalId":20048,"journal":{"name":"Photonics Research","volume":"296 1","pages":"4510"},"PeriodicalIF":7.6,"publicationDate":"2026-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149089865","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}

Here, we present a compact submicron-precision exact-constraint (SPEC) six-axis positioning stage for sensor-free registration of detection focal planes in a three-color fluorescence micro-optical sectioning tomography (fMOST) system. By integrating an exact-constraint mechanism with partial motion decoupling, optimized preload, and a natural frequency of 982 Hz, the stage achieves robust anti-vibration performance under 180 Hz vibratome sectioning. A data-driven open-loop compensation method eliminates systematic and hysteresis errors, yielding translational accuracy better than 1 μm and rotational accuracy within 30 μrad. Combined with a dual-step registration pipeline, the system attains sub-pixel alignment accuracy (<0.33 μm ) across three channels. High-fidelity multicolor imaging of fluorescently labeled mouse brain slices demonstrates precise subcellular co-localization of neurons, astrocytes, and nuclei without post-processing registration. This compact, cost-effective, and sensor-free SPEC platform offers a versatile solution for reliable multicolor 3D fluorescence imaging in neuroscience and histopathology.","PeriodicalId":20048,"journal":{"name":"Photonics Research","volume":"24 1","pages":"4489"},"PeriodicalIF":7.6,"publicationDate":"2026-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149089863","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}

However, generating Poincaré beams (PBs) whose single or multiple SoPs can be arbitrarily switched in space with a single input beam remains challenging, because conventional polarization-control schemes rely on a beat-interference mechanism that forces SoPs to evolve continuously along the propagation axis. Here, we demonstrate a phase-polarization joint strategy based on the principle of mode extraction (PoME) and an optical pen (OP) technique. By breaking the intrinsic modulation symmetry of a high-order vector vortex beam and harnessing polarization-mode competition among the liberated eigenmodes, our approach selectively amplifies a target polarization while naturally suppressing non-target components, achieving mode selection within a single incident beam without external polarization separation or recombination. Combined with the OP’s spatial-addressing capability, arbitrary PBs on both the fundamental and higher-order Poincaré spheres can be discretely and independently extracted at prescribed locations along the propagation path. We employ Bessel beams (BBs) for their diffraction-resistant and self-healing properties, which are well suited to long-distance SoP extraction. This work provides new perspectives for spatial polarization manipulation, with advantages in applications such as parallel laser manufacturing, high-dimensional optical quantum metrology, information encryption, and deep-biological imaging and sensing.","PeriodicalId":20048,"journal":{"name":"Photonics Research","volume":"2 1","pages":"4541"},"PeriodicalIF":7.6,"publicationDate":"2026-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149089898","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}

However, in conventional metamaterial-based thermal radiation control schemes, although narrowband emission can be achieved, the spatial divergence angle is usually passively determined by the intrinsic properties of the resonant mode, making it difficult to design it actively and continuously as an independent variable. Therefore, achieving a designable compression of the divergence angle while maintaining a narrow bandwidth remains an unresolved challenge. Here, we propose and validate an extremely directional narrowband thermal emission strategy based on a radiative-loss jump mechanism. Specifically, the resonance wavelength of a high-quality-factor quasi-bound state in the continuum (quasi-BIC) is deliberately locked to the critical point ( λ 0 = p ) at which the −1st-order diffraction channel of a periodic structure opens. Near this singular point, the radiative loss of the system exhibits a divergent response to angular variations, thereby forcing the thermal radiation energy to be confined within an extremely narrow angular window defined by the diffraction boundary. More importantly, by tuning the detuning between the resonance wavelength and the critical point, continuous and active control of the divergence angle can be achieved. This work not only demonstrates an extremely directional narrowband thermal emitter with an actively designable divergence angle but also reveals the physical mechanism by which the spatial modes of thermal radiation can be ultimately compressed by precisely locking a high- Q quasi-BIC resonant mode to the diffraction critical point and exploiting the associated radiative-loss jump. These findings provide a theoretical foundation for shifting narrowband directional thermal emitters from passive optimization toward controllable design.","PeriodicalId":20048,"journal":{"name":"Photonics Research","volume":"8 1","pages":"4433"},"PeriodicalIF":7.6,"publicationDate":"2026-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149088887","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}

However, for resonators at the scale of tens of micrometers, the experimental Q factor has long been limited to the order of 1 million. Here, we propose a silicon-based stepped Euler-bending microdisk resonator (MDR) that achieves record-breaking performance. This research introduces an innovative structural design approach that combines suspended architecture with multi-step sidewalls and Euler-bending boundaries to overcome fundamental limitations in conventional disk resonators. The device demonstrates an ultra-high experimental intrinsic Q factor of 4.8×10 7 while maintaining a compact footprint of merely 1.29×10 −3 mm 2 . Compared to state-of-the-art integrated resonators, the proposed MDRs truly break the constraints between the device size and Q factor. Furthermore, the proposed design methodology addresses critical challenges in achieving both ultra-high Q factors and fabrication tolerance in micrometer-scale devices. Consequently, the developed micrometer-scale ultra-high- Q resonator holds the potential to revolutionize on-chip high-density communication networks and unlock advanced signal processing. This work establishes a new paradigm for developing compact and high-performance optical resonators, which can be extended to diverse material platforms including silicon nitride and lithium niobate.","PeriodicalId":20048,"journal":{"name":"Photonics Research","volume":"399 1","pages":"4399"},"PeriodicalIF":7.6,"publicationDate":"2026-09-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149020132","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}
