Study of tapered microfibers by line-field confocal optical coherence tomography

Key Points

• The aim is to measure the core and cladding diameters of tapered silica microfibers using line-field confocal optical coherence tomography (LC-OCT).
• Utilized line-field confocal optical coherence tomography (LC-OCT) for measurements.
• Focused on tapered silica microfibers.
• Monitored changes in core and cladding diameters during the tapering process.
• First-time measurements of core and cladding diameters in tapered microfibers were obtained.
• The findings show the evolution of these diameters as the microfiber tapers.
• Results suggest potential for refining models of optical mode propagation.
