20.500.12556/RUL-178021 Microwave photonic techniques in phase-noise measurements of microwave sources a review of fiber-optic delay-line methods Microwave photonics has recently come to the forefront as a valuable approach to generating, processing, and measuring signals in high-performance domains such as communication, radar, and timing systems. Recent studies have introduced a range of photonics-based phase-noise analyzers (PNAs) that utilize a variety of architectures, including phase detection, frequency discrimination, and hybrid mechanisms that combine optical with electronic processing. This review focuses on microwave photonic techniques for phase-noise measurement based on the fiber-optic delay-line method, by exploring their fundamental principles, system design frameworks, and performance indicators. The fiber-optic delayline method is examined as the core architecture, due to the exceptionally low loss and wide bandwidth of the optical fiber, which enable long delays and high measurement sensitivity. Through the integration of insights garnered from recent publications, our objective is to deliver a comprehensive understanding of the strengths and limitations associated with fiber-optic delay-line-based PNAs and to pinpoint new and promising areas for advancing research in the field of oscillator metrology. microwave photonics phase-noise measurement optical fiber delay-line method photonic processing sensitivity improvement mikrovalovna fotonika merjenje faznega šuma optično vlakno postopek s kasnilnim vodom fotonska obdelava izboljšanje občutljivost true false true Angleški jezik Slovenski jezik Članek v reviji 2026-01-16 09:53:19 2026-01-16 09:53:24 2026-01-17 04:38:19 0000-00-00 00:00:00 2026 0 0 18 str. issue 1 [article no.] 60 Vol. 13 Jan. 2026 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 621.39 2304-6732 10.3390/photonics13010060 264941315 photonics-13-00060.pdf photonics-13-00060.pdf 1 9EA75E902A0C30CAEAD2AA32DA1F424C 9ef62235026bc11b444da9836c3c0d6382f09204538cc49738d9d60fbda90848 f97ecbe1-f2b8-11f0-bf92-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=225518 https://www.mdpi.com/2304-6732/13/1/60 1 c7e4f6bb-f2b8-11f0-bf92-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=225517 Fakulteta za elektrotehniko 0 0 0
