Aleksandr Razumov

Aleksandr Razumov is a Postdoctoral Researcher at the Department of Electrical and Photonics Engineering, Technical University of Denmark (DTU), focusing on phase noise characterization in photonic systems. His work integrates advanced signal processing with optical engineering to enhance frequency comb stability for telecommunications and metrology applications.

Razumov earned his PhD from DTU in 2025 with a thesis titled "Subspace Tracking for Phase Noise Characterization of Optical Frequency Combs", supervised by Professor Darko Zibar. His educational background centers on photonics and signal processing methodologies.

His research spans Phase Noise analysis, Optical Frequency Comb technology, and algorithm development including Subspace Tracking and Bayesian Filtering. These efforts target noise reduction in laser systems, with direct applications in optical communications and precision measurement. Key collaborations include DTU researchers like Mirov, Da Ros, and Zibar.

Recent publications (2024-2025) reveal a concentrated focus on subspace-based noise characterization techniques, demonstrating methodological evolution from foundational tutorials to specialized comb applications. This trajectory highlights growing sophistication in tackling noise sources within Cr:ZnS laser systems.

No scientific awards are documented in available records, though his work shows measurable impact through conference presentations and journal publications.

Razumov contributes to DTU's photonic research ecosystem as both a recent PhD graduate and active postdoc, continuing his doctoral project "Subspace Tracking for Phase Noise Characterization of Optical Frequency Combs" (2022-2025) without indication of external grants or student supervision.
