    Illustrations showing microplanktons (green) being imaged with a holographic microscope. The holograms (shown at the bottom) act as a unique fingerprint of the microplankton dry mass and vertical distance.
    Supplemented with artificial intelligence, a new holographic microscopy approach offers a better understanding of one of the ocean’s more important, and most mysterious, creatures...

    FIGURE 1. Coordinated, Distributed, Real-time Decisions and Actions across a dynamic and heterogeneous battle space require a large amount of data to be collected, processed, and communicated between platforms. This demands individual platforms have unprecedented access to the electromagnetic spectrum, with the corresponding intra-platform capability to capture, process, and transport large spectral datasets.
    Lockheed Martin has partnered with Ayar Labs to replace traditional electrical interconnects with optical I/O solutions.

    FIGURE 1. Schematic of the experimental setup. Both the Bell state source and polarization qubit memory are realized as all-optical loops. Polarization-resolved detection of one photon triggers the FPGA (center of the picture), which in turn controls the quantum memory by acting on an electro-optic modulator. At the output of the memory, the photons’ polarization is detected. QWP: quarter-wave plate; HWP: half-wave plate; DM: dichroic mirror; PBS: polarizing beam splitter; EOM: electro-optic modulator.
    Researchers in Germany create the first programmable all-optical buffer quantum memory capable of dynamically switching back and forth between storage mode, interference mode,...

    A schematic of DopaFilm shows spatially resolved hotspots of activity (top) and DopaFilm’s fluorescent nanosensors glow brighter when exposed to dopamine (bottom).
    By measuring the release of dopamine and other neurotransmitters, a composite material can help provide a better understanding of chemical neurotransmission.

    Spatial light modulator used to shape the structure of two photons to generated the desired quantum state.
    The Gouy phase for quantum light is not only different than its classical counterpart, its origin can be linked to another quantum state.

    For light sheet 3D printing, red and blue lasers are used to print objects precisely and quickly at a micrometer scale.
    A group of researchers in Germany and Australia created a 3D-printing resin that gets irradiated simultaneously by crossed red and blue laser beams, along with a dedicated 3D ...
