The purpose of this work is to determine the optimal deposition process (DP) parameters such as precursor concentration (C), carrier gas pressure (P), substrate temperature (T), and solution flow rate (F) to optimize the multiple performances such as optical transmittance (TR), roughness (RO), and thickness (TH) of the ZnO thin-films fabricated by spray pyrolysis. This work proposed a new methodology for multiple performances optimization of ZnO thin-films DP using some popular multi-criteria decision making (MCDM) and Taguchi method, and determined the optimal DP parameters. The optimal DP parameters combined with 3 MCDMs (SAW, TOPSIS, and GRA) and Taguchi method were C of 0.2 M, P of 1.0 bar, T of 415 °C, and F of 4 mL/min, respectively. The influence ranking (magnitudes) of the DP parameters was T (29.946%), P (26.507%), C (25.099%), and F (18.448%). The methodology could be widely applied to not only ZnO thin-films DP optimization by spray pyrolysis but also many advanced manufacturing technology process optimization problems.</p></div>","PeriodicalId":722,"journal":{"name":"Optical Review","volume":"33 4","pages":"623 - 635"},"PeriodicalIF":1.0,"publicationDate":"2026-08-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148728778","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"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 PSi layers have been produced using two techniques: pulsed laser (PL) ablation etching and electrochemical etching. Pulsed laser deposition (PLD) was used for depositing 300 nm-thick ZnPc thin films onto both the prepared PSi substrates and standard n-type silicon. Atomic force microscopy (AFM), UV-visible spectrophotometry, and X-ray diffraction (XRD) have been used for examining the morphological, structural, and optical characteristics of ZnPc films. Current-voltage (I-V) parameters have been examined in both dark and UV light (310 nm, 4 W). The findings show that, in comparison to both chemically etched PSi and conventional Si substrates, the detector employing PL-ablated PSi substrate performs noticeably better. A photocurrent gain of 15.01, responsivity of 75.61 mA/W, and a quantum efficiency of 3 × 10<sup>− 1</sup> are important figures of merit. The total response time was 2.457 s, the rise time (10–90%) was 0.847 s, and the fall time (90–10%) was 1.61 s. The study demonstrates that laser-ablated porous silicon effectively enhances the surface area and improves charge carrier dynamics, leading to superior UV detection performance compared to conventional Si-based detectors.</p></div>","PeriodicalId":722,"journal":{"name":"Optical Review","volume":"33 4","pages":"636 - 643"},"PeriodicalIF":1.0,"publicationDate":"2026-08-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148728779","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"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}

Utilizing the Maxwell stress tensor to evaluate optical forces, it is shown that the DCP configuration overcomes the inherent axial instabilities of single-beam traps by canceling scattering forces. The results reveal that DCP RP BBs provide superior three-dimensional trapping stiffness than DCP LP BBs due to strong longitudinal electric field components, creating a stable potential well ideal for assembling uniform nanoparticle arrays. Conversely, DCP AP BBs generate a hollow-core intensity distribution that traps particles in ring-like arrays. This work is expected to deepen the understanding of the interactions between spherical nanoparticles and DCP structured light fields, and provide theoretical guidance for long-range, multi-particle manipulation in complex optical environments.</p></div>","PeriodicalId":722,"journal":{"name":"Optical Review","volume":"33 4","pages":"644 - 652"},"PeriodicalIF":1.0,"publicationDate":"2026-08-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148728780","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"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 influence of alloy composition x on steady and dynamic characteristics is comprehensively analyzed at room temperature (RT). Small-signal frequency anlysis demonstrates that the modulation bandwidth and the relaxation response decrease with increasing alloy composition x. Consequently, low alloy composition x preserve strong resonance behavior and a wider − 3 dB modulation bandwidth, while increasing alloy composition x reduces the small-signal modulation bandwidth and damping of the relaxation oscillation response. The maximum − 3 dB modulation bandwidth of approximately 47 GHz is achieved at an injection current of 6 mA for the lowest alloy composition (x = 0.4%). These results highlight the strong dependence of VCSEL on alloy composition x and dememonstate that low N incorporation can optimize device efficiency, while excessive alloy composition x significantly degrades modulation speed and overall performance. The originality of this work resides in establishing a direct alloy composition dependence of the rate equation parameters, enabling to identification of an optimal composition range for both extended wavelength and enhanced device performance.

Conventional Mach–Zehnder interferometer (MZI)-based waveguide optical switches suffer from crosstalk at the through port when the optical power coupling ratio of directional couplers deviates from the optimal value of 0.5. In this study, the operating characteristics of optical switches composed of two MZIs cascaded mirror-symmetrically or point-symmetrically are numerically analyzed and compared with that of a single-stage MZI. The results show that, in the mirror-symmetrically cascaded configuration, crosstalk appears at the through port when the coupling ratio deviates from the optimal value, similar to the single-stage MZI. In contrast, in the point-symmetrically cascaded configuration, crosstalk at both the through and cross ports can be theoretically eliminated by appropriately adjusting the phase difference in the ON state. These results indicate that the point-symmetrically cascaded configuration provides high robustness against fabrication errors and is an effective structure for realizing high-performance optical switches without requiring complex control schemes.</p></div>","PeriodicalId":722,"journal":{"name":"Optical Review","volume":"33 3","pages":"480 - 488"},"PeriodicalIF":1.0,"publicationDate":"2026-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148682327","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"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}

To improve the theoretical framework of CIE and related industry standards and to strictly ensure equality between CCTs of the reference illuminant and test light source, this study proposes a nonlinear least-squares optimization method to modify the combination coefficients of CIE D-Series. Furthermore, to investigate the influence of the improved algorithm on the CIE <i>R</i><sub>f</sub> index, 417 illuminants were selected for the evaluation.

The evaluation results demonstrate that the proposed method ensures the consistency of CCT between the test and reference illuminants while having no impact on the calculation of the color fidelity index.

To analyze the optical response characteristics of complex multi-sphere soot aggregates, this paper systematically calculates and analyzes the scattering matrices and polarization properties across several typical lidar wavelengths based on the Cluster–Cluster Aggregation (CCA) model and using the Multiple Sphere T-matrix (MSTM) method. By examining the effects of scale parameters, microstructural parameters, and size parameters separately, this study analyzes the modulation of light scattering characteristics in complex fractal clusters by multiple factors. The results indicate that scale parameters significantly influence the scattering and polarization responses of soot clusters; under short-wavelength conditions, forward scattering is enhanced, and certain polarization parameters exhibit higher sensitivity to structural changes; as the wavelength increases, the differences in polarization responses among clusters with different structures gradually diminish, showing a trend toward convergence with the response of an equivalent spherical particle. The influence of microstructural parameters on polarization characteristics exhibits distinct wavelength dependence, while the modulating effect of an increased number of primary monomers on certain polarization parameters tends to level off over a relatively large range of N. Overall, the influence of scale parameters and overall size parameters on polarization scattering characteristics is relatively more pronounced. The multi-wavelength, multi-parameter comparative analysis framework established in this study can provide a numerical simulation reference for the inversion of black carbon aerosol microphysical parameters using multi-wavelength polarization lidar.</p></div>","PeriodicalId":722,"journal":{"name":"Optical Review","volume":"33 3","pages":"489 - 503"},"PeriodicalIF":1.0,"publicationDate":"2026-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148783222","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"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}
