For a fiber length of 200 μm, the structure attains a crosstalk (CT) value of 137.0 dB at 1.31 μm. Furthermore, it exhibits a bandwidth of 1.04 μm with CT levels exceeding 20 dB, spanning the wavelength range from 1.16 to 2.2 μm. The same elliptical PCF structure can also function as a RI sensor, achieving a sensitivity of 8600 nm/RIU within a sensing range of 1.29–1.31. Additionally, replacing the elliptical holes with fully circular holes in the proposed fiber maintains a wide polarization-filtering bandwidth and yields a high RI sensitivity of 21,400 nm/RIU over the range 1.37–1.39. These results indicate that fully circular holes based on the proposed PCF structure represent a viable alternative for applications in both polarization filtering and RI sensing.</p></div>","PeriodicalId":722,"journal":{"name":"Optical Review","volume":"32 5","pages":"728 - 736"},"PeriodicalIF":0.9,"publicationDate":"2025-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145384732","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}

In the dawn of HS imaging, HS imaging relied primarily on time-consuming scanning techniques to achieve high spatial and spectral resolution, limiting its applicability. Subsequently, snapshot (non-scanning) HS imaging emerged, enabling high-speed capturing. The snapshot method captures HS images in a single exposure, but it has the drawback of lower spatial resolution. With recent advancements in computational technology, high-efficiency HS imaging has been pursued in cooperation with image post-processing. In this review, the historical evolution of HS imaging is described focusing on spectroscopic techniques. An up-to-date HS imaging technique, computational HS imaging using a spatial-spectral random coded mask, is introduced with a brief explanation of its working principle. The HS imaging technique demonstrates outstanding characteristics in terms of sensitivity, spatial resolution, spectral accuracy, and frame rate. Several applications of HS imaging are introduced showing improved accuracy of image analysis compared to traditional RGB image analysis.

However, system performance is highly sensitive to environmental factors such as absorption, scattering, turbulence, and noise. This study presents a comprehensive, simulation-based performance analysis and optimization of UOWC systems using Opti-System software, focusing on laser diodes operating at 450 nm and 520 nm. Four representative water types—pure seawater, clear ocean, coastal ocean, and turbid harbor—are examined to evaluate key performance metrics, including received power, Q-factor, eye diagrams, signal-to-noise ratio (SNR), bit error rate (BER), and transmission range. An environment-aware optimization framework is proposed, correlating wavelength selection and system configurations with the optical properties of each water type. The impact of transmitter power, beam divergence, photodetector sensitivity, and modulation (OOK) is assessed to identify optimal design choices for robust communication. Simulation results reveal that shorter wavelengths perform better in clearer waters, while adaptive tuning strategies significantly enhance reliability in highly scattering or turbulent conditions. This work provides practical design insights and optimization strategies to support scalable, efficient, and resilient UOWC systems for real-world IoUT applications.</p></div>","PeriodicalId":722,"journal":{"name":"Optical Review","volume":"32 5","pages":"684 - 704"},"PeriodicalIF":0.9,"publicationDate":"2025-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145384731","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}

Conventional two-directional pupil expansion using beam splitter array (BSA) waveguides often suffers from low light coupling efficiency and degraded image quality due to narrow coupling mirrors and wavefront disturbances caused by exposed mirror edges along the total internal reflection surface. We propose a novel HMD optical system that combines a pupil expansion (PE) prism with a one-directional BSA waveguide. The PE prism features an enlarged coupling surface, efficiently capturing light from the light engine. Importantly, the PE prism is designed to avoid exposed mirror edges in the optical path, thereby eliminating wavefront disturbances and enabling high-resolution virtual image projection. Within the PE prism, multiple ray paths are generated through complex reflections and transmissions via overlapping multi-mirrors. This multi-path propagation not only expands the eye-box orthogonally to the BSA waveguide, but also ensures uniform output luminance. A prototype HMD implementing the proposed method achieves high luminance (over 5000 cd/m<sup>2</sup>), high image resolution (MTF > 58% at 10 cycles/degree), high optical see-through transparency (over 94%), and luminance uniformity (over 53%).
