    FIGURE 1. Uses of fiber transmission in 5G networks and their exterior connections in datacenters and the global network. Inside the wireless system, fibers connect central offices and local data centers to cell towers and to small 28 GHz cells placed on buildings or poles.
    With 5G wireless networks spreading around the world, standards writers are turning to optical communications for high wireless bandwidths over short distances.

    In dual-comb digital holography, as many holograms as there are comb lines are created.
    A new technique, hyperspectral digital holography, is advancing and enriching conventional holography with optical frequency combs.

    These images of human lung carcinoma cells and mouse skeletal muscle cells illustrate the performance of various resolution enhancement procedures. The left column presents low-resolution images downsampled from the high-resolution images in the second column. The new AI model results are in the right-most column, outperforming other reconstruction techniques in metrics of both accuracy and realism.
    A team of researchers has demonstrated a generative adversarial network (GAN)-based approach that allows budget-priced optics to produce high-resolution cellular images.

    By using entangled photons and interference effects, Fraunhofer researchers can record infrared spectra of molecules (in this case methane) via cameras that only detect visible light.
    Fraunhofer researchers are developing quantum optical solutions for wavelength ranges that have so far remained inaccessible.
