He is also a member of professional organisations such as IEEE, Optica (OSA), and SPIE, and serves as a topic board member for the journal Sensors.
Dr Jasim had to lead high-impact research in specialty optical fibres at the Czech Academy of Sciences. His most recent work (2024–2025) shifts towards the sensitivity of hollow-core fibres to environmental factors and the application of advanced fabrication techniques.
Latest Research (2024–2025)
- Acoustic Vibration Sensitivity: A major focus of his 2024 and 2025 conference papers is the interaction between light and acoustic waves in Negative Curvature Hollow-Core Fibers (NC-HCF). This research explores how fibre geometry influences sensitivity to audible spectrum vibrations.
- Optical Frequency Dissemination: In early 2025, he co-authored work on transferring precise optical frequencies through hollow-core fibres, a critical step for next-generation communication and sensing networks.
- Laser-Aided Fabrication: A key 2025 publication details the impact of CO2 lasers and grinding on shaping optical fibre preforms to reduce inner-cladding losses in double-clad fibres.
- Bandpass Spectral Filters: He has recently developed all-fiber bandpass filters based on NC-HCF technology, improving how light is filtered within the fibre itself.
Fibre Designs & Innovation
His documented designs at the Institute of Photonics and Electronics focus on:
- Hollow-Core Photonic Crystal Fibers (HC-PCFs): Designs optimized for broadband radiation and low-loss transmission.
- Anti-Resonant Fibers: Developing nested tubular elements that reduce confinement loss, enabling ultra-low loss in the visible light spectrum.
- Thermally Shaped Double-Clad Fibres: Innovative geometries designed to optimise pump absorption and thulium-doped fibre performance.
Current Roles & Metrics
- Editorial Work: He remains a Topic Board Member for the journal Sensors (MDPI).
- Scientific Impact: His h-index and citation count continue to grow, with a career total of over 70 publications and significant citations in the fields of Mach-Zehnder interferometers and RE-doped nanoparticles.
