Abstract
Multi-core optical fibers are widely used for information transfer and endoscopy. However, dispersion effects result in phase noise of the transmitted light fields, limiting applications. This can be characterized holographically. We investigate the use of laser ablation to apply holograms for correcting the phase noise. We show that the desired phase correction can be applied via intensity modulation. We compare the phase shift of single-shot vs multi-shot ablation. Additionally, the ablation is compared to additive manufacturing and digital optical phase conjugation. The presented results demonstrate, that phase corrected light field transfer is possible via optical fibers.
