Owing to the restricted optical cross-sectional area of the 220 nm-thick silicon layer, conventional SOI platform is incapable of managing the nonlinear optical losses and thermal loads induced by high-power continuous-wave (CW) light. For high-power applications, we propose a strategy that combines a 500 nm-thick silicon layer with 800 nm-wide waveguide beyond single mode regime. Experimental results confirm that the proposed waveguide sustains a stable transmission at 1550 nm wavelength under a high input power, and, compared with the single-mode waveguide, exhibits a higher on-chip power threshold and a relatively lower nonlinear loss. Based on this platform, we demonstrate a 64-element two-dimensional optical phased array (OPA) with a uniform circular aperture design with footprint of 3 mm × 2.5 mm and fabricated with a standard silicon photonics process. By incorporating efficient calibration algorithm, we achieve a sidelobe suppression ratio (SLSR) exceeding 4.45 dB at the central direction and a two-dimensional beam steering over a 10° × 8° field of view with SLSR greater than 3.1 dB.","PeriodicalId":13204,"journal":{"name":"IEEE Photonics Journal","volume":"18 1","pages":"1-6"},"PeriodicalIF":2.6,"publicationDate":"2026-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=11339873","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148481260","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To the best of our knowledge, this is the first numerical demonstration of such a concept using moving index perturbations. We numerically study the signal dynamics under the influence of a moving refractive index front in optical waveguides, revealing analogies to relativistic event horizon physics. Our simulations show that a free-carrier-induced refractive index front, which lowers the refractive index and induces a blue shift in the waveguide’s band diagram, can overtake and trap a signal pulse, dynamically accelerating it to the front's velocity. As the interaction continues, the signal is eventually released from the front and transitions into a new velocity regime. This process of trapping, acceleration, and release mirrors the behavior of light near gravitational horizons, with the release phase analogous to light escaping a white hole. These results pave the way for new approaches in nonlinear optics and signal processing using compact, chip-scale systems.","PeriodicalId":13204,"journal":{"name":"IEEE Photonics Journal","volume":"18 1","pages":"1-6"},"PeriodicalIF":2.6,"publicationDate":"2026-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=11354509","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148480564","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This work presents the design of electro-optic modulators on thin-film lithium niobate capable of addressing this burgeoning data requirement. Slow-wave enhancement of the effective modulation length has not yet shown potential for commercialization due to velocity or index mismatch between the optical carrier field and the RF-modulation signal. This work addresses this deficiency by designing slow-wave-matched electrodes and optical waveguides with corrugated gratings to achieve a modulator with a 1.25 V DC half-wave voltage, while maintaining greater than 100 GHz of bandwidth. This result provides the opportunity for seamless integration with complementary metal-oxide-semiconductor electronics without the use of power-hungry RF preamplifiers for mid- and long-haul fiber-optic communications.","PeriodicalId":13204,"journal":{"name":"IEEE Photonics Journal","volume":"18 1","pages":"1-7"},"PeriodicalIF":2.6,"publicationDate":"2026-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=11328810","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148480901","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper proposes a quantum message authentication code (QMAC) leveraging quantum mechanics to achieve robust security. The QMAC uses quantum one-way functions (QOWFs) to convert encrypted classical bits into qubits. This approach fundamentally differs from the computational hardness assumptions of conventional MACs. The QMAC’s security is computationally difficulty-independent based on the inherent properties of quantum mechanics, making it impervious to exhaustive search attacks. Additionally, the protocol integrates authentication directly into the secure communication framework, obviating the need for extra particles and reducing computational complexity compared to stabilizer code-based or controlled unitary operations. Through a rigorous security analysis, we demonstrate the resilience of the proposed QMAC protocol against a wide range of adversarial strategies, including interception–resend attacks, identity impersonation, and entanglement-based attacks, among others.","PeriodicalId":13204,"journal":{"name":"IEEE Photonics Journal","volume":"18 1","pages":"1-11"},"PeriodicalIF":2.6,"publicationDate":"2026-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=11352865","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148481375","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, prior research has primarily focused on stable aberrations and the influence of hypersonic flow fields on aero-optical mechanisms under various boundary conditions, while the dynamic characteristics of these effects and aberrations remain comparatively underexplored. This study investigates the dynamic features of aero-optical effects by analyzing their spectral properties and aberration variations over varying exposure durations. The influence of changes in Mach number, altitude, and angle of attack on these dynamic characteristics is thoroughly examined. This study also assesses the temporal accumulation of aberrations in the image plane during exposure. The findings reveal that the average primary frequency of aberrations is notably higher than that of the aero-optical effects. Optimal image quality is achieved within an exposure duration of approximately 81–82% at a fixed altitude. In most instances, third-order polynomial linear regression effectively models image quality variations with increasing exposure durations, with fitted results yielding R<inline-formula><tex-math>$^{2}$</tex-math></inline-formula><inline-formula><tex-math>$geq$</tex-math></inline-formula>0.85.

Most efforts have been directed towards incremental improvements in fabrication techniques. In this work, a systematic simulation-driven approach is proposed to optimize GaN/AlGaN nanowire (NW)-based photonic crystal (PhC) laser structures, which have potential applications in disinfection, sensing and non-line-of-sight communications. The method employs 1-dimensional and 2-dimensional solvers to pre-screen leaky designs and refine the structural parameters, which are then further analyzed using 3-dimensional simulations for the final optimization. A new physical analysis of the PhC mode and its diffracted components is proposed. This analysis provides insight into the interplay between PhC, NW, and air modes and its effect on the performance of NW PhC lasers. A simplified approach to the complex multi-parameter optimization problem for NW waveguide structures is developed that not only improves the performance of UV lasers but also establishes general design principles for surface-emitting NW-based PhC lasers. These guidelines are primarily concerned with ensuring that structures accommodate the PhC mode well, which depend on the layer thicknesses of the NW waveguide. Implementing these guidelines can result in more than a 60-fold improvement in the NW PhC laser performance. It is further suggested to optimize for surface output efficiency rather than Q-factor and introduce absorption losses once a suitable structure has been found. This framework represents a robust and computationally efficient pathway for future development in optimizing the NW waveguide design, paving the way for cost-effective and high-performance UV light-emitting devices.","PeriodicalId":13204,"journal":{"name":"IEEE Photonics Journal","volume":"18 1","pages":"1-14"},"PeriodicalIF":2.6,"publicationDate":"2026-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=11268963","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148480074","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There is a need of computer assisted diagnostic companion of the pathologist that provides objectivity and workflow efficacy.
