These technologies have the potential to democratize access to high-quality diagnostic tools by providing innovative solutions for analyzing medical images. Dermatological diagnostic processes — such as dermatoscopy, microscopy and smartphone-assisted dermatology — can be paired with AI to support medical experts to enhance accuracy and efficiency. This review systematically surveys the current scientific literature on techniques that employ intelligent systems both for dermatological diagnostics, as well as dermatopathology. Key deep learning methodologies, such as convolutional neural networks (CNNs), transfer learning, and explainable AI, are examined in the context of current medical practices. The analysis also addresses practical challenges, such as image quality, computational constraints, and data privacy. Throughout the review, emerging trends and future directions are identified, such as AI-integration as an assisting technology, and microscopy as a facilitator for intelligent system development in global healthcare.

In this work, we have constructed a 1 μm dual-wavelength fiber laser based on a cascaded resonant cavity with fiber Bragg gratings (FBGs), and the dual-wavelength laser output at the central wavelengths of 1060 nm and 1080 nm was simultaneously achieved. The laser performance involving output power and spectral evolution of this dual-wavelength fiber laser were carefully compared and investigated under two different cascading configurations, including 1060-1080 and 1080-1060. The experimental results reveal that the 1060-1080 configuration was more favorable for the dual-wavelength fiber lasers to generate high-power and high-spectral-purity dual-wavelength laser compared to the 1080-1060 configuration. Furthermore, based on the 1060-1080 configuration, a continuous-wave dual-wavelength laser output at 1060 nm with 40.43 W and 1080 nm with 302.65 W was simultaneously achieved, with the nonlinear effect suppression over 40 dB at the maximum power. To the best of our knowledge, this is the first demonstration of 1 μm cascaded resonant cavity dual-wavelength fiber laser. This work offers a significant guidance for designing and implementing the high-power compactness dual-wavelength fiber laser within 1 μm spectral region.","PeriodicalId":13204,"journal":{"name":"IEEE Photonics Journal","volume":"17 3","pages":"1-7"},"PeriodicalIF":2.1,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10945714","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143848826","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}

In this work, we first proposed and experimentally demonstrated a highly efficient 2D grating coupler enabled by exciting multipolar resonances through bi-level dielectric structures. A 70-nm shallow-etched hole array and a 160-nm-thick deposited polycrystalline silicon tooth array are employed in our proposed 2D grating coupler. Strong optical field confinement and enhanced radiation directionality can thus be attained through the use of 193-nm deep-ultraviolet (DUV) lithography, which is readily accessible from commercial silicon photonics foundries. The measured experimental peak coupling efficiency is −2.54 dB with a minimum feature size of 180 nm. Due to the benefits of perfectly vertical coupling, the measured polarization-dependent loss in our experiments is below 0.3 dB within the 3-dB working bandwidth. Our proposed multipolar radiation mode enhanced 2D grating structure can also be applied to other integrated optics platforms, enabling an efficient and polarization-diversity coupling between optical fibers and photonic chips while reducing requirements on feature size.","PeriodicalId":13204,"journal":{"name":"IEEE Photonics Journal","volume":"17 2","pages":"1-6"},"PeriodicalIF":2.1,"publicationDate":"2025-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10945688","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143824660","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}

By utilizing the phase-matching coupling of SiO<sub>2</sub>/Si-confined modes, the devices with the gratings demonstrate a high absorbance peak of ∼97% with an ultra-narrow linewidth of ∼1 nm at 1550 nm.

The single-tone signal utilizes a phase-shift method for high-precision ranging, while the pseudo-random code is employed to solve the distance ambiguity problem in the phase-shift method. The merging of the pseudo-random code with the single-tone signal in the digital domain and the data processing in the digital domain achieve simultaneous modulation and simultaneous ranging, which ensures the complete synchronization of the two signals during both transmission and processing. Furthermore, the pseudo-random code is band-limited, which ensures that the pseudo-random code signal and the single-tone signal do not overlap spectrally, thus preventing interference between them.

This work is placed in context and compared with results provided by other authors, showing the relevance of the outcomes and subsequent future possibilities. It also creates a discussion in which the performance of other fiber technologies may be compared, as new B5G fronthauls with special attention paid to transmission in a single fiber, avoiding noise transfer between high power laser PoF source and 5G-NR data that affects the signal quality. PoF energy delivery efficiencies are also analyzed, achieving up to 9.9 % efficiency (from launched optical power to electrical power on the load) for a 3.1 km HCF and 0.9 % for a 11.1 km HCF.

The system's performance is evaluated in a 5 km 28 GBaud 16 QAM transmission scenario. The simulation results indicate that error-feedback noise shaping (EFNS) is highly effective in suppressing digital-to-analog converter (DAC) quantization noise, thereby reducing resolution demands on the DAC. Furthermore, the adaptive equalizer, based on a Stokes-domain depolarization scheme (SS-AEQ), achieves a 45% reduction in the complexity of the equalization algorithm.
