    In an ideal optical fiber, rotating the input cleanly rotates the output. That’s not the case in real fibers. Characterization of this effect leads to new practical applications. Read go.aps.org/4emXf5o @WFShaping @BrombergYaron @GuyPelc @Adv_Imaging_Lab #PRXOptics

    Characterization and Exploitation of the Rotational Memory Effect in Multimode Fibers
    In an ideal optical fiber, rotating the input cleanly rotates the output. That's not the case in real fibers, thanks to imperfections. Characterization of this effect, however, leads to new practical...

    New preprint: we show wavefront shaping with a new kind of MEMS megapixel spatial light modulator that has fast pistoning micro-mirrors: arxiv.org/abs/2409.01289 (includes code to run it fast). Great effort from project lead José @carl00s01, also with @gsdgordon @joelacarpenter.
