Making a step toward simplification, this work proposes and experimentally demonstrates a cloud-inspired deployment scenario that off-loads and centralizes complexity inherent to high-quality light sources that are traditionally hosted by interrogator units. By replacing the high-coherence source with optically synchronized “proxy” sources that resemble traditional telecom lasers, the complexity of field-distributed interrogators can be reduced without striking unfavorable performance trade-offs: Even though the required synchronization process is facilitated over a massive optical budget of 42 dB – or 37.5 dB when additionally taking long-term wavelength excursion due to sub-optimal laser control into account, the induced vibration phase along a probed fiber span can be correctly acquired. Moreover, a sharing factor of more than 1:4000 is established for the centralized high-coherence source by eroding the available feeder budget through a power-split based dissemination network that shares narrow-linewidth light seed among a large number of interrogator units.","PeriodicalId":16144,"journal":{"name":"Journal of Lightwave Technology","volume":"44 16","pages":"7015-7022"},"PeriodicalIF":5.2,"publicationDate":"2026-08-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148719055","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Furthermore, we introduce an innovative blind source separation (BSS) method based on degenerate unmixing estimation technique (DUET) to enable the separation and localization of multiple concurrent vibration events along the sensing fiber link without any prior knowledge, by utilizing the signals collected from two counter-propagating interferometers, which provides a competitive solution to the long-standing challenge of multipoint localization in interferometric distributed optical fiber sensors.","PeriodicalId":16144,"journal":{"name":"Journal of Lightwave Technology","volume":"44 16","pages":"7291-7299"},"PeriodicalIF":5.2,"publicationDate":"2026-08-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148718971","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The key to deriving PCFM is expressing the spatial power profile of each channel along a span as a polynomial. Then, under reasonable approximations, the integral calculation can be carried out analytically, for any chosen degree of the polynomial. We present a full detailed derivation of the model. We then validate it vs. the numerically integrated GN-model in a 60/100 km challenging multiband (C+L+S) scenario, including Raman amplification and inter-channel Raman scattering. We then show that the approach works well also in the special case of the presence of multiple lumped loss along the fiber. Overall, the approach shows high reliability and broad generality, achieving a generalized Signal-to-Noise Ratio (GSNR) accuracy of nonlinear interference (NLI) within 0.3 dB of the GN-model benchmark.

Although many photonic-based microwave generation methods have achieved breakthroughs in noise and bandwidth, surpassing the limitations of conventional electronic devices, they still face challenges in broadband tunability and trade-offs among noise level, system complexity, and operating frequency. In this work, we investigate a continuously tunable and low-noise photonic microwave generation approach based on optical heterodyning. Compact MgF<sub>2</sub> whispering-gallery-mode micro-disk resonators incorporating non-vacuum thermal insulation and vibration-isolation were fabricated as optical reference cavities. Under ambient conditions, two semiconductor lasers are independently locked to the two references via the Pound-Drever-Hall frequency stabilization technique, and their heterodyne beat produces continuously tunable millimeter-wave signals spanning 80 GHz − 100 GHz. At a 100 GHz carrier frequency, the system achieves a phase noise of −98 dBc/Hz at 10 kHz offset and a fractional frequency stability of 6×10<sup>-10</sup> at 1 s averaging time. This method holds strong potential for further miniaturization and packaging through photonic integration, offering a widely accessible low-noise millimeter-wave source for next-generation communications, quantum technologies, and precision measurements.","PeriodicalId":16144,"journal":{"name":"Journal of Lightwave Technology","volume":"44 16","pages":"7118-7124"},"PeriodicalIF":5.2,"publicationDate":"2026-08-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148719006","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
