  2. Recent developments in the understanding and passive mitigation of transverse mode instability

    Year of publicationStatusReview pendingPublished in:Optical fiber technology : materials, devices and systems C. Jauregui, Y. Tu, S. Kholaif, F. Möller, G. Palma-Vega, N. Haarlammert, T. Walbaum, T. Schreiber, J. Limpert
    In this article we look at the newest developments in the understanding and mitigation of TMI in single-core fibers. This includes recent quantitative measurements that reveal the dependence of the TMI threshold on the modal content of the seed, systematic measurements on the dependence of the TMI threshold on the fiber core size, as well as the study of TMI in PM fibers including a novel passive mitigation strategy and the static modal energy transfer recently observed in these fibers.

  11. Multiplexing information limits in multi-beam ptychography

    Year of publicationPublished in:Optics Express D. Penagos Molina, W. Eschen, C. Liu, J. Limpert, J. Rothhardt
    Ptychography is a lensless imaging technique where the sample is laterally scanned by the illuminating beam. In multi-beam ptychography multiple beams simultaneously illuminate the sample, enabling faster scanning of larger areas. In this work, we explore the potential of multi-beam ptychography with a large number of illumination channels to enhance imaging throughput. Our findings show that while spatial resolution is reduced compared to single-beam ptychography, multi-beam ptychography still significantly increases throughput. Using synthetic and experimental data, we demonstrate an almost fivefold improvement in throughput, accompanied by reduced memory footprint and overhead time. Furthermore, we present the successful implementation of massively multiplexed multi-beam ptychography with up to 64 channels. These results pave the way for efficient use of light sources with partial spatial or temporal coherence for ptychography, opening new possibilities for high-throughput imaging applications.
